In △XYZ, angle X is the smallest angle, angle Y is 40 degrees more than angle X, and angle Z is 2 times the measure of angle X.
What is the measure of angle X?
1 answer:
Answer:
x=35° y= 75° z = 70°
Step-by-step explanation:
Y = x+40 (known)
z = 2x (known)
x + y + z = 180 (triangle property)
x + (x+40) + 2x = 180 (substitution)
4x + 40 = 180
4x = 140
x = 35
y = x + 40 = 75
z = 2x = 70

Justin's statement would be the best. In order to change 3/5 into 6/10, both sides would need to be multiplied by 2.
A. 70°
Supplementary angles always = 180°
Where 180 - 110 = 70
110+ 70 = 180
Answer:
Step-by-step explanation:
its 22.00 or just 22
Step-by-step explanation:
by using similarity and enlargement
10/8 = 7+y/7
70=56+8y
8y=14
y= 7/4
10/8 = 5+x/5
50=40+8x
x = 8/10 = 4/5
