Answer:

70°

Step-by-step explanation:

∠A =112°,

Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)

Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x

∠A + ∠B + ∠C = 180 (sum o angles in a triangle)

112 + 180 - 2x + 168 - 2x = 180

460 - 4x = 180

4x = 460 - 180 = 280

x = 280/4 = 70

x = 70°

Plz help me with this unknown side length in right triangle
aniked [119]

Answer:

7 sqrt(2)= BC

7 sqrt(2)= AB

Step-by-step explanation:

sin 45 = opp / hyp

sin 45 = BC / 14

Multiply each side by 14

14 sin 45 = BC

Sin 45 = sqrt(2)/2

14 sqrt(2)/ 2 = BC

7 sqrt(2)= BC

cos 45 = adj / hyp

cos 45 = AB / 14

Multiply each side by 14

14 cos 45 = AB

cos 45 = sqrt(2)/2

14 sqrt(2)/ 2 = AB

7 sqrt(2)= AB

Model B

Step-by-step explanation:

First, solve what each model means:

Model A:

6 boxes, 2 shaded

2/6=1/3

1/3 is approximately 33.35

Model B:

8 boxes, 3 shaded

3/8 is 37.5%

this is the answer, but we can go ahead and check the other boxes

Model C:

5 boxes, 2 shaded

2/5 is 40%

Model D:

7 boxes, 3 shaded

3/7 is approximately 42.9%

HELPPPPPP what number would you add to -8 to make 0
MrMuchimi

Hello!

your answer is: 8

-8 is just 8 below zero, so adding 8 would bring it back to zero.

for example, 0 - 8 = -8, therefore: -8 + 8 = 0

I hope this helps, and have a nice day!
