Answer:
Hello heloo it's my first question so IAm just writing any thing
Answer:
105
Step-by-step explanation:
because all the angles added up have to = 180
60+15=75
75-180=105
Answer:
ANGLE 1 = 40°
Step-by-step explanation:
angle 1 = angle 2 ------(alternate interior angles)
2x + 20 = 3x + 10
20 - 10 = 3x - 2x
x = 10.
Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.
HOPE IT HELPS!!!
You could use the substitution method. in this you’ll solve one equation for one variable. we’ll do the first one for y.
add 3x to both sides, so y = 3x + 2
then add that into the other equation for y.
7x - 8(3x +2) = 1
7x- 24x - 16 = 1
-17x - 16 = 1
-17x = 17
x= -1
now that you know what x is, you can find out y with the equation we made earlier. y = 3x+2
y = 3(-1) + 2
y = -3 + 2
y = -1
