If c is the hypotenuse of a right triangle,find the missing side. If necessary, round to the nearest hundredth. c=sqrt(155), b=s

Lunna [17]

A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)

Find the measures of the complementary angles that satisfy each case. One of the angles is 3 times larger than the other.

Nookie1986 [14]

Answer:

22.5° and 67.5°

Step-by-step explanation:

The sum of complementary angles equal 90°.

Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.

Thus, the following expression can be written to represent this case:

$x + 3x = 90$

Solve for x

$4x = 90$

Divide both sides by 4

$\frac{4x}{4} = \frac{90}{4}$

$x = 22.5$

The measure of the complementary angles are:

x = 22.5°

3x = 3(22.5) = 67.5°

What is 3/5+3/8 in simplest form

schepotkina [342]

The answer would be 39/40.

1. Find the LCD of both of the fractions (LCD = 40)

2. Make the denominators the same as LCD (The LCD would be 40)

3. Simplify (24/40 + 15/40)

4. Join the denominators (24 + 15/40)

5. Simplify (39/40)

In decimal form its 0.975.
