What is the measure of angle B in the triangle?<br><br> This triangle is not drawn to scale.
Kazeer [188]

Answer: m\angle B=70\°

Step-by-step explanation:

By definition, the sum of the interior angles of a triangle is 180 degrees.

Based on this, you need to set up the following equation:

40+(2x-30)+(x+20)=180

The next steo is to solve for "x" in order to find its value. This is:

40+2x-30+x+20=180\\\\30+3x=180\\\\3x=180-30\\\\3x=150\\\\x=\frac{150}{3}\\\\x=50

You can observe in the picture of the triangle ABC given in the exercise, that:

m\angle B=(2x-30)\°

Therefore, you must substitute the value of "x" into that equation and then evaluate, in order to find the measure of the angle B. This is:

m\angle B=(2(50)-30)\°\\\\m\angle B=(100-30)\°\\\\m\angle B=70\°

What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42°?
blsea [12.9K]

Answer:

96 degrees

Step-by-step explanation:

you have two angles that each measure 42 degrees, giving you 84 degrees combined

there are 180 degrees in a triangle, therefore the vertex angle is equal to 180 minus 84, or 96 degrees

check:

42 + 42 + 96 = 180

180 = 180
