90 + 20x + 10x = 180
30x = 90
x = 3
Answer:
0.875
Step-by-step explanation:
9.85-8.975 equala 0.875
Answer:
110 degrees, 84 degrees
Step-by-step explanation:
Picture 1:
See attached image for the angles I am referencing.
measure of angle a= measure of the 110 degree angle because of corresponding angles
measure of angle b=measure of angle a because of vertical angles
Therefore, through transitivity, we can state that the measure of
angle b= angle a= 110 degrees
Picture 2:
angle x=84 degree angle through alternate interior angles.
Answer: 2.1
Step-by-step explanation:
3.4 - 2.8d + 2.8d - 1.3
add the variables together and the coefficients or add the d's with d's and 3.4 with 1.3
= 3.4 - 1.3 = 2.1
=2.8d - 2.8d = 0
The final answer would be 2.1
