Answer:
35 degrees
Step-by-step explanation:
This is because the angles in a triangle are equal to 180 degrees.
So you would add the 90 degrees (because it is a right angled triangle) with the 55 degrees which would give you 145 degrees.
You would minus that from 180 degrees and that gives you 35 degrees.
Hope this helps:)

Answer:
Answer:
Silk = x = 1.5 yards
Cotton = y = 2.75 yards
Step-by-step explanation:
x + y = 4.25
16.90x + 4y = 36.35
1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.
2.
x + y = 4.25 (1)
16.90x + 4y = 36.35 (2)
Multiply (1) by 4
4x + 4y = 17 (3)
16.90x + 4y = 36.35 (2)
Subtract (3) from (2)
16.90x - 4x = 36.35 - 17
12.90x = 19.35
Divide both sides by 12.90
x = 19.35 / 12.90
= 1.5
x = 1.5 yards
Substitute x = 1.5 yards into (1)
x + y = 4.25
1.5 + y = 4.25
y = 4.25 - 1.5
= 2.75
y = 2.75 yards
Silk = x = 1.5 yards
Cotton = y = 2.75 yards

Answer:
A
Step-by-step explanation: im not extremely sure about this one though but the x coordinate is nine away from every coordinate of defc and the way it goes left means that the x is negative, the y coordinates of defc prime is positive because it moves up from defc. hope this helps
