Answer:22 and 21
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
4+4=8, 26-8=18, 18 <em>/ </em>2 = 9, and this is 100% right becuase I got it right on Khan Academy
Hello!
First we have to find the measurement of angle SRU.
180 - 84 = 96
96/2 = 48
Angle SRU = 48 + 90 = 138
All angles in a triangle add the 180
180 - 138 - 30 = 12
The answer is B)12°
Hope this helps!
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
That would happen when the factors have opposite signs.
