56° and 34°
complementary angles sum to 90° thus
3x - 10 + 2x - 10 = 90
5x - 20 = 90
add 20 to both sides of the equation
5x = 90 + 20 = 110
divide both sides by 5
x = = 22
angle 2x - 10 = (2 × 22) - 10 = 44 - 10 = 34° and
angle 3x - 10 = (3 × 22) - 10 = 66 - 10 = 56°
Answer:
Part A: 25% of 50 = 12.5
Part B: 25% of 60 = 15
Part C: 50% of 60 = 30
Part D: 75% of 60 = 45
Part E: 75% of 30 = 22.5
Part F: 100% of 22.5 = 22.5
Part G: 10% of 22.5 = 2.25
Part H: 50% of 45.7 = 22.85
Step-by-step explanation:
To find - Do you know the answer to
Part A: 25% of 50 =
Part B: 25% of 60 =
Part C: 50% of 60 =
Part D: 75% of 60 =
Part E: 75% of 30 =
Part F: 100% of 22.5 =
Part G: 10% of 22.5 =
Part H: 50% of 45.7 =
Proof -
Part A :
25% of 50 = =
= 12.5
⇒25% of 50 = 12.5
Part B :
25% of 60 = =
= 15
⇒25% of 60 = 15
Part C :
50% of 60 = =
= 30
⇒50% of 60 = 30
Part D :
75% of 60 = =
= 45
⇒75% of 60 = 45
Part E :
75% of 30 = =
= 22.5
⇒75% of 30 = 22.5
Part F :
100% of 22.5 = = 22.5
⇒ 100% of 22.5 = 22.5
Part G :
10% of 22.5 = = 2.25
⇒ 10% of 22.5 = 2.25
Part H :
50% of 45.7 = =
= 22.85
⇒50% of 45.7 = 22.85
