Answer:
What to know about the lines is the exact point is 0 what you need to know to find that is answer 1, 2 and 3
Step-by-step explanation:
Plug it in
7(4) + 8(5) which would be 28 + 40
Answer: 68
Answer there is no choice, but it is x+1/3+2 1/2.
Step-by-step explanation:
Step-by-step explanation:
mXYZ+mXYW=180°(being straight angle)
mXYW =180-115
mXYW=65
now,
mXWY+mWXY+mXYW=180°(sum of angle of triangle)
mXWY=180-110
mXWY=70°
hope it helps.
Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
