Answer:
39.5
Step-by-step explanation:
angle ABC=60=(5x+2)+(3x-2)
60=8x
x=7.5
Angle ABD=(5x+2),(sub x=7.5)
=(5*7.5+2)
=39.5

4 Does the answer that’s what I got on my quiz I just took the test
Answer:
D
Step-by-step explanation:
Straight line (straight angle) is always 180 degrees.
The angle adjacent to 115 and 115 degree angle would sum up to 180 (straight line).
So, that angle would be:
180 - 115 = 65
Now, we know the triangle's 2 angles: 85 (given) and 65 (found), thus we can find the third angle (leftmost):
85 + 65 + third angle = 180 [sum of 3 angles in a triangle is 180]
150 + third angle = 180
third angle = 180 - 150
third angle = 30
This third angle is adjacent to w and forms a straight line, so we can write:
third angle + w = 180
30 + w = 180
w = 180 - 30
w = 150
Correct answer is D
The equation in point slope form is y-1 = 1/4(x - 12)
<h3>Equation of a line</h3>
The formula for calculating the equation of a line is expressed as;
y = mx + b
m is the slope
b is the intercept
Slope = 1+3/12+4
Slope = 4/16
Slope = 1/4
For the intercept
1 = 1/4(12) + b
b = 1 - 3
b = -2
Hence the equation in point slope form is y-1 = 1/4(x - 12)
