In triangle ABC, it is given that A = 70 degree, B = 52 degree, BO and CO are the bisectors of angle B and angle C
respectively. Find angle OCB andangle BOC.

Answers

Answer 1

Answer:

Angle OCB= 35 degrees and Angle BOC= 119

Step-by-step explanation:

ANGLE OCB= 1/2 C (Construction of bisector)

= 1/2 70

= 35

ANGLE OBC= 1/2 B (Construction of bisector)

= 1/2 52

= 26

Therefore, in triangle BOC,

180 degree= ANGLE OBC+ANGLE BOC+ANGLE OCB

180= 35+26+ANGLE BOC

180= 61+ANGLE BOC

ANGLE BOC= 180-61

ANGLE BOC= 119

Answer 2

Answer:

angle ocb=58°

angleboc=96°

Step-by-step explanation:

first get the measure of angle acb which is 58°

this is becoz the total angles in a triangle add up to 180°

angle cbo =26° and angle bco=58°

therefore to get the remaining angle boc ,u add 58 &26 ,then minus from 180

the answer is 96°

A square field has 3,844 sq. meters of land. What is the width of the field?

Answers

Answer:

The side length is 62 meters

Step-by-step explanation:

The area of a square is given by

A = s^2  where s is the side length

3844 m^2 = s^2

Take the square root of each side

sqrt( 3844 m^2) = sqrt(s^2)

62 m= s

The side length is 62 meters

A bag contains 3 red marbles, 8 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be green?

Answers

Answer:

A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.

Total = 18 marbles.

Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.

Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

Solve this equation
100x + 300 = 200

Answers

Answer:

-1

Step-by-step explanation:

100x=200-300

100x=-100

100x/100=-100/100

x=-1

After solving this equation we get, 100x + 300 = 200 x = -1.

To solve this equation

100x + 300 = 200,

Subtract 300 on both side,

100x + 300 - 300 = 200 - 300

100x = -100

Divide 100 on both side,

x = -1

Therefore, After solving this equation 100x + 300 = 200 we get x = -1.

D. [tex] l = \frac{P - 2w}{2} [/tex]

Step-by-step explanation:

Given:

[tex] P = 2l + 2w [/tex]

Required:

Solve for l

Solution:

To solve for l, we would make l the subject of the given formula.

[tex] P = 2l + 2w [/tex]

[tex] P = 2(l + w) [/tex]

Divide both sides by 2

[tex] \frac{P}{2} = \frac{2(l + w)}{2} [/tex]

[tex] \frac{P}{2} = l + w [/tex]

Subtract w from both sides

[tex] \frac{P}{2} - w = l + w - w [/tex]

[tex] \frac{P}{2} - w = l [/tex]

[tex] \frac{P}{2} - \frac{w}{1} = l [/tex]

[tex] \frac{P - 2w}{2} = l [/tex]
