nataly862011 [7]

Answer:

Step-by-step explanation:

You need the Pythagorean Theorem to solve this question. There is no be part.

Equation

c^2 = a^2 + b^2

Givens

a = 32

b = 21

c = ?

Solution

c^2 = a^2 + b^2              Substitute the values

c^2 = 32^2 + 21^2          Expand

c^2 = 1024 + 441            Combine

c^2 = 1465                     Take the square root of both sides

√c^2 = √1465  

c = 38.275

Answer: 38.3 rounded

the measure of 2 complementary angles are in the ratio 1:4. what are the degree measures of the 2 angles
BaLLatris [955]

Angles are 18° and 72°

Step-by-step explanation:

  • Step 1: Find the two complementary angles in the ratio 1:4. Let the angles be 1x and 4x.

x + 4x = 90° (∵ they are complementary)

5x = 90

∴ x = 90/5 = 18

⇒ Angles are 18° and 4x = 72°
