36/25 is your answer mate :)))
Answer:
A
Step-by-step explanation:
4x^2-8x-60=0
a=4 b=-8 c=-60
*I am going to plug these numbers into the quadratic formula*
x=-(-8)plus or minus 
*simplified into...
x=-8 plus or minus 
x=5 or x=-3
pls mark me brainliest
Step-by-step explanation:
Answer:
40. x = 106 degrees
41. x = 118 degrees
Step-by-step explanation:
40.
straight line has 180 degrees
180 - 128 = 52 : angle inside triangle
180 - 126 = 54 : angle inside triangle
52 + 54 = 106
triangle has 180 degrees
180 - 106 = 74 : 3rd angle inside the triangle
again straight line has 180 degrees
180 - 74 = 106 = x
41.
shape of 4 sides is 360 degrees
180 - 34 = 146
little box means one the sides is 90 degrees on either side
146 + 90 = 236
360 - 236 = 124
both x's are the same so angles inside are the same too
124 ÷ 2 = 62
straight line is 180
180 - 62 = 118
x = 118
Answer:
50
Step-by-step explanation:
The inside of a triangle equals 180 and so you subtract the other two values(100 and 30) to 180 and you get 50.
