Missing angles in triangles worksheet

A.) = 40°   B.) = 90°   C.) = 53.5°   D.) = 34°   E.) = 90°   F.) = 52.9°   G.) = 90°

H.) = 59.6°   I.) = 119.1°  J.) = 30.4°   K.) = 90°   L.) = 72°   M.) = 107.3°

N.) = 47.7°  O.) = 36°   P.) = 90°

Step-by-step explanation:

All triangles are 180°

So:

A.) 72 + 68 = 140     180 - 140 = 40

The little boxes in the triangle indicates that the angle is a right angle. Right angles are 90°

B.) Is a right angle

C.) 36.5 + 90 = 126.5    180 - 126.5 = 53.5

D.) 56 + 90 = 146    180 - 146 = 34

E.) Is a right angle

F.) 95 + 32.1 = 127.1        180 - 127.1 = 52.9

G.) Is a right angle

H.) 30.4 + 90 = 120.4   180 - 120.4 = 59.6

To find angle I you have to find angle J first. So, because there is a box. That indicates that both angle equal 90°.

So you have to subtract H from 90° H = 59.6

J.) 59.6 - 90 = 30.4

I.) 30.5 + 30.4 = 60.9    180 - 60.9 = 119.1

K.) 45 + 45 = 90  180 - 90 = 90

L.) 33 + 75 = 108   180 - 108 = 72

M.) 37 + 35.7 = 72.7  180 - 72.7 = 107.3

N.) 92.3 + 40 = 132.3  180 - 132.3 = 47.7

O.) 54 + 90 = 144  180 - 144 = 36

P.) Is a right angle

Hope this helps : )

i just took the test, the correct answer is .. 31.5 in.

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
