Two angles in a triangle measure 33 and 112 What is the measure of the third angle?

Answers

All the angles of a triangle always add up to 180 degrees.

For now, x represents the missing angle.
180 = 33 + 112 + x

Add 33 + 112.
180 = 145 + x

Subtract 145 from both sides.
35 = x

So, the measure of the third angle is 35 degrees.

Answer:

35 I got it right on the test.

Simplify.–1 + 5(6 – y)



A.


–y + 5


B.


–y + 29


C.


–5y + 29


D.


–5y – 31

Answers

The answer is C. This is because you have to expand the brackets
-1+5(6-y)
The -1 remains the same but the bracket changes.
-1+30-5y
This is because the 5*6 is 30 and 5*y is 5y
This can be simplified to
29-5y or -5+29

31,50 is 42% os what number

Answers

(31,50)/(x)=(42)/(100)

The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.


(31.50)/(x) = (42)/(100)\n\ncross\ multiply\n\n31.50*100=3150\n42* x=42x\n\n3150=42x\nx=75
Your answer is 75.
