It’s 75! 65+40= 105 then 180-105= 75
densk [106]2 years ago

Answer:

75 degrees

Step-by-step explanation:

All the interior angles of a triangle add up to 180 degrees. Knowing this, we can construct the following equation:

180=65+40+x

180=105+x

Subtract both sides by 105

180-105=105+x-105

75=x

Therefore, angle C has a measure of 75 degrees.

I hope this helps!

measure a and measure b are vertical angles with measure a = x and measure b = 4x - 30. what is measure a?
Zolol [24]

Answer:

∠a = 10°

Step-by-step explanation:

The measure of ∠a = x

The measure of ∠b = 4x-30

It is also mentioned that the measure a and measure b are vertical angles. We need to find the value of a.

For vertically opposite angles,

∠a = ∠b

x = 4x-30

or

4x-30=x

Taking like terms together,

4x-x= 30

3x = 30

x = 10

So, the meausre of ∠a is equal to 10°.
