Find each measurement. Assume that each figure is not drawn to scale.
ivanzaharov [21]

Answer:

1) 2 1/4 inches (2.25)

2) 5.3 millimeters

3) X=10 and YZ=60

Step-by-step explanation:

Number 1, you just add the measurements because n and q is the start and end of the line segment.

Number 2, you are given the whole measurement, and you know FG which is 9.7, so you subtract the 15 (whole measurement) by 9.7, which is 5.3.

Number 3, you know that XY and YZ equal XZ, so 8x+1 would equal 81. Do the math, you would get 8x=80 and then x=8. Now you know x, plug it in for 6x, so 6(10)=60.

Mariulka [41]

Answer: angle y is 50°

Step-by-step explanation:

t + 2t - 30 = 90

3t -30 = 90

3t = 90+30

t = 120/3 = 40 = angle X

Angle y = 2t-30

y = 2*40-30

=80-30 = 50
