Answer:
1) 145°
2) 20°
3) x = 7 ; measurement of the missing angle = 24
Step-by-step explanation:
1) supplement = 180°, 180 - 35 = 145
2) complment = 90° , 90 - 70 = 20
3) the figure is a right angle so the measurement is 90°
66 + (4x-4) = 90
62 + 4x = 90
4x = 28
x = 7
4(7) - 4
28 - 4
= 24
Answer:
6.6 yd
Step-by-step explanation:
+
=
+=
Substitute a= 10 and c=12
100+=144 Evaluate the Powers
=44 Subtract 100 on both sides.
b=
Square root both sides b>0 so you dont need ⊥
b=6.6 Use a calculator to evaluate.
