Answer:
30°
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in any triangle is 180°. A right triangle has one angle that is 90°, so the sum of the remaining two acute angles is 180° -90° = 90°. That is, the acute angles in a right triangle are complementary.
__
The other acute angle is ...
90° -60° = 30°

Which of the following means greater than or equal to?
A. Aleast
B. Maximum
C. Not greater than
D. At most
Answer:
at least
Step-by-step explanation:
i don't know how to fully explain it, but by saying "atleast x" you're saying the minimum value it can be will be x. Maximum means it will not exceed that number, along with "not greater than" and "at most"
In the figure below, L is parallel to M. Find X
Answer:
Let's first try to find the angle supplementary to measure 141°.
(Supplementary angles are two angles that add up together to equal 180°).
Set up an equation;
141 + x(unknown angle measure) = 180°
Solve for x:-
141 + x = 180
-141 -141
x = 39°.
Now that we've found one of the interior angles measure to this triangle, we will use this value to figure out the angle measure next to 'x'.
If we think of the line (highlighted in the picture I attached to this), extended, we can kind of make out of this line as a transversal cutting into the two parallel lines(L & M).
Furthermore, the measured angle 39°, is an alternate interior angle with the missing angle next to 'x'(highlighted with yellow in my picture).
And, alternate interior angles are congruent(meaning they measure the same degree).
Therefore, we can infer that the missing angle next to 'x' is also 39°.
Now that we've found one angle measure and another angle(given) next to x, we can see that angle x and those two angle measures (48° and 39°) combined are supplementary!
So now that we know that angles 48° and 39° are supplementary with x, we can find the value of x by finding it's supplement value!
Arrange an equation;
(48 + 39) + x = 180°
Simplify and solve for x:-
87 + x = 180
-87 -87
x = 93°, hence ∠X = 93°.

In one week, Neha spends hours cooking and y hours cleaning.
The time she spends cleaning is at least equal to the time she spends cooking.
This can be written as y > r.
She spends no more than 16 hours in total cooking and cleaning.
What are the two inequalities in x and /or y to show this information
Answer:
Y ≥(greater than or equal to) R or Y ≤(less than or equal to) R
The phrase at least means about equal to, represented by that sign. In this case, equal to, because x + y = 16 total since she spent 16 hours cooking and cleaning. That would mean they both have to equal 8 to get 16. You can also do 10 + 6 to get 16. There are a few more solutions after this you can try, which I will not list at the moment.

The perimeter of the rectangle below is 222 units find the length of side RS
Answer:
111
Step-by-step explanation:
divide 222 by 2 and you get your answer
Answer:
55.5
Step-by-step explanation:
since we don't know the length or width of any side, one length side will only be 1/4 of 222. And perimeter is all the sides added up. This rectangle will actually be a square.
222/4=55.5
simplify 15a+21b-6a-4
Answer:
9a+21b-4
Step-by-step explanation:
first of all combine the like terms
15a + 21b - 6a - 4
= 9a + 21b - 4 Ans.
The simplified expression of 15a+21b-6a-4 is 9a+21b-4
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 15a+21b-6a-4
Fifteen times of a plus twenty one times of b minus six times of a minus four.
a and b are the variables and plus, minus are the operators
Add the like terms in the expression
15a-6a+21b-4
Fifteen times of a and minus six times of a are the like terms.
So add these like terms.
When 15 and -6 are added we get 9
So the expression becomes as Nine times of a plus twenty one times of b minus four.
9a+21b-4
Hence, the simplified expression of 15a+21b-6a-4 is 9a+21b-4
