Answer:
51 degrees
Step-by-step explanation:
All right angles are 90 degrees and all triangles interior angles add up to 180.
39+90=129
180-129=51
(3,0)(0,4)
slope = (4 - 0) / (0 - 3) = -4/3
A perpendicular line will have a negative reciprocal slope. So our perpendicular line has a slope of 3/4
y = mx + b
slope(m) = 3/4
(-6,-5)....x = -6 and y = -5
now sub into the formula and find b, the y int
-5 = 3/4(-6) + b
-5 = -18/4 + b
-5 + 18/4 = b
-20/4 + 18/4 = b
-2/4 = b
so ur perpendicular line is : y = 3/4x - 2/4....or 3x - 4y = 2
and ur point (6,4) lies on the perpendicular line <===
Answer:
$81.6
Step-by-step explanation:
You multiply 0.2 by 68, in which you will get 13.6, and then you add that to 68.
Answer:
90
Step-by-step explanation:
Answer:
2.68
Step-by-step explanation:
2/4=1.34/x
solve proportion
2x=5.36
divide both sides by 2
5.36/2
=2.68
