triangle abc has angle measures as shown.
b. what are the values of angles a and b? show your work.

x = 30; m<A = 25; m<B = 120  

Step-by-step explanation:

The sum of the measures of a triangle is 180 degrees.

Therefore m<A + m<B + m<C = 180

In other words,

(x -5) + (3x + 30) + 35 = 180, or

4x + 60 = 180, which means 4x = 120 and x = 30.

The measure of angle A = x - 5 = 30 - 5 = 25

The measure of angle B = 3x + 30 = 3(30) + 30 = 120

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
