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\°

First 4 terms for 5 - 2n
vlabodo [156]

Answer:

3 , 1 , -1 , -3

Step-by-step explanation:

5 - 2n

n = 1 ;  5 - 2n = 5 - 2*1 = 5 - 2 = 3

n = 2;  5 - 2n = 5 - 2*2 = 5 - 4 = 1

n = 3;  5 - 2n = 5 - 2*3 = 5 - 6 = -1

n = 4;  5 -2n = 5 - 2*4 = 5 - 8 = -3

First 4 terms are :  3 , 1 , -1 , -3
