Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
When the two angles add to 180 grades, we say they "supplement" each other.
Answer:
The angle of CAD is 100°.
Step-by-step explanation:
Given that total angles in a triangle is 180° so you will have to find the angle of CAB :
∠CAB + ∠ACB + ∠ABC = 180°
∠CAB + 80° + 20° = 180°
∠CAB + 100° = 180°
∠CAB = 180° - 100°
∠CAB = 80°
Next, you have to subtract it from 180° because straight line have a degree of 180°
∠CAD = 180° - 80°
∠CAD = 100°
Answer:
318 in^2
Step-by-step explanation:
Area of a rectangle = length x width
16 x 13 1/4
16 x 53/4 = 212 in^2
10 1/3 + 10 1/4
