Answer:
y = -x + 17
Step-by-step explanation:
A(-10,-3)
B(7,14)
C(5,12)
Need line CD perpendicular to AB through C.
Solution:
slope of AB, m1 = (yb-ya) / (xb-xa) = (14- -3) / (7- -10) = 17/17 = 1
Slope of CD, m2 = -1/m1 = -1 / 1 = -1
Line CD through C, using the point slope form
y-yc = m2(x-xc)
y-12 = -1 (x-5)
rearrange
y = -x + 5 + 12
y = -x + 17
0.008 as a percent is 0.8%.
Answer:
22.5
Step-by-step explanation:
i have gotten this question before so im for sure its 22.5
The two interior angles of the triangle is 75 and 105 degree.
<h3>What is the exterior angle theorem ?</h3>
According to the exterior angle theorem , The size of an exterior angle of a triangle is the sum of of smaller of two opposite interior angles.
It is given that
Let the measure of the two interior angle be x and y
then
The size of an exterior angle of a triangle is the supplement of smaller of two opposite interior angles
x+ y = 180
the greater of the opposite interior angles exceeds the smaller by 30 degrees , find the measure of the interior angles of the triangle.
x = y+30
By substitution method
y+30+y = 180
2y +30 = 180
2y = 150
y = 75 degree and x = 105 degree.
Therefore the two interior angles of the triangle is 75 and 105 degree.
