Answer:
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

The missing angles are
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°
The Sum of angles in a triangle is 180 degrees. Therefore,
A = 180 - 72 - 68 = 40 degrees(sum of angles in a triangle)
B = 90 degrees(right angle)
C = 180 - 90 - 36.5 = 53.5 degrees(sum of angles in a triangle)
D = 180 - 90 - 56 = 34 degrees(sum of angles in a triangle)
E = 90 degrees(right angle)
F = 180 - 95 - 32.1 = 52.9 degrees(sum of angles in a triangle)
G = 90 degrees(right angle)
H = 180 - 90 - 30.4 = 59.6 degrees(sum of angles in a triangle)
I = 180 - 30.4 - 30.5 = 119.1 degrees(sum of angles in a triangle)
J =90 - 59.6 = 30.4 degrees
K = 180 - 45 - 45 = 90 degrees(sum of angles in a triangle)
L = 180 - 75 - 33 = 72 degrees(sum of angles in a triangle)
M = 180 - 35.7 - 37 = 107.3 degrees(sum of angles in a triangle)
N = 180 - 40 - 92.3= 47.7 degrees(sum of angles in a triangle)
O = 180 - 90 - 54 = 36 degrees(sum of angles in a triangle)
P = 90 degrees(right angle)
