(a) An angle measures 40°. What is the measure of its complement?
3 answers:
<h2>
( a) </h2>
If the sum of the measures of two angles is 90° they are known as complementary angles.
Let the value of unknown angle be x.
According to the question
⇨x + 40° = 90°
⇨x = 90° - 40° [Subtract]
⇨x = 50°
Complement angle is 5 0 °

( b) </h2>
If the sum of the measures of two angles is 180° they are known as supplementary angles.
Let the value of unknown angle be x.
According to the question
⇛x + 63° = 180°
⇛x = 180° - 63° [Subtract]
⇛x = 117°
Supplement angle is 1 1 7 °
Answer:
see below
Step-by-step explanation:
Complements add to 90 degrees
x+40 = 90
x = 90-40
x = 50
Supplements add to 180
y+63 =180
y = 180-63
y = 117

Answer: 22.14 (22.1428571429)
Step-by-step explanation:
OK
Let's Start with the equation
0.7(x−7)−4.9=5.7
Add 4.9 to both sides
0.7(x-7)=10.6
Divide both sides by 0.7
x-7= 15. 1428571429
Add 7 to both sides
x= 22.1428571429 or 22.14
