Measure of angle A=180- Measure of angle C + Measure of angle B
2x=180-(90+3x)
2x=180-90-3x
+3x. +3x
5x=180-90
5/5x=90/5
x=18
Measure of angle is
A= 2x
A=2(18)
A=36

Measure of angle B =
3x
3(18)
54

Simply, Measure of angle A is 36, Measure of angle B is 54 and measure if angle C is 90

Solve the Answer for x.<br> 56 &lt; 7(7-x)
Ierofanga [76]

Answer:

x < -1

Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />56 < 7(7 - x)

56 < (7 * 7) + (7 * -x)

56 < 49 - 7x

<u>Step 2:  Subtract 49 from both sides</u>

<u />56 - 49 < 49 - 7x- 49

7 < -7x

<u>Step 3:  Divide both sides by -7</u>

<u />7 / -7 < -7x / -7

Since you divided by a negative, you must flip the sign.

<u />7 / -7 < -7x / -7

-1 > x

Answer:  x < -1

Hello! Don't worry! I will try to answer this as best as I can and as fast as I can. Sorry if the answer is wrong. I am still learning.

The earthworm length is longer than 6.0 cm because the worm needs to

be straightened.

The choice is true because the image clearly illustrates that the earthworm is screwed into a part of its body. To make a proper measurement the earthworm must be fully stretched and measured from the head to the extreme tip of the "tail"

Hope this helps you!

:).
