The measure of an angle is 63.6°. what is the measure of a complementary angle?

Tanzania [10]

Complementary angles add up to 90°.

You are given one angle that is 63.6°.

Let's make the other angle "x".

63.6 + x = 90

To find x, all you have to do is subtract the other angle (63.6) from 90.
90 - 63.6 = 26.4
x = 26.4

The measure of the complementary angle is 26.4°.

kaits younger sister is 2feet and 9 inches tall.katie is 5 feet and 4 inches tall . what is the difference between their two hig

Bess [88]

Answer:

$2\ ft\ 7\ in$

Step-by-step explanation:

we know that

To find the difference convert the dimensions to inches

Remember that

$1\ ft=12\ in$

so

katie's younger sister hight is

$2\ ft\ 9\ in=2*12+9=33\ in$

katie's hight is

$5\ ft\ 4\ in=5*12+4=64\ in$

Find the difference

$64\ in-33\ in=31\ in$

Convert to feet and inches

$31\ in=31/12=(24/12)+(7/12)=2+(7/12)=2\ ft\ 7\ in$

sattari [20]

Domain: -4, -1, 6, 8, 9

Range: -2, 0, 4, 5

Domain can easily be found by looking through the set's x-coordinates.

Range can be found on the y-coordinates.

Repeating numbers just needs one number to be listed (Ex. the range has two 4's but there is only one 4 listed).

Write them in order.
