Answer:

i think it's A.) 5.5

Step-by-step explanation:

A right triangle has 90°

Given: 15 and 20

15 + 20 = 35

90 - 35 = 55

55 is the missing angle

Round to the nearest tenth: 55 ÷ 10 = 5.5

Please help ASAP it is due today
Dmitrij [34]

Answer:

Step-by-step explanation:

What we know

total sum of angles = 540 deg

3/2 b cam also be written as 1.5b degrees.

So 1.5b + (b+45) + (2b - 90) +90 = 540

Step 1 -- get rid of parenthesis

         1.5b + b + 45 +2b -90 +90 =540

Step 2 -- combine the like expressions

         4.5b + 45 = 540

Step 3 -- subtract 45 from both the sides

         4.5b = 495

Step 4 -- divide 4.5 from both the sides

         b = 110  ----- not the right answer

Thats not right okay im sorry

but i guess if it is not 110 it should be 100, 90 etc.

90 = b is correct
