58 degrees

Explanation
If you have a triangle with the angle measures of abc as 58 degrees, 102 degrees and 20 degrees you can multiply them in order of abc so 58 degrees is angle a, 102 degrees is angle b and 20 degrees is angle c. Then you just put in angle a for d which would be 58 degrees and angle e for b 102 degrees and angle f for c which would be 20 degrees

What is the y-coordinate of the midpoint of WU? A 2.5 B. -1.5 C. -0.5 D. 1.5

lilavasa [31]

Option C: -0.5 is the right answer

Step-by-step explanation:

Given is the graph on which different points are indicated.

We have to find the y-coordinae of the mid-point of WU.

The formula for mid-point is:

$(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

So we only have to know the y-coordinates of both points to find the mid-points y coordinate

So by observing the graph we get

y_1 =0

y_2 = -1

So,

$\frac{0-1}{2}\\= \frac{-1}{2}\\= -0.5$

Hence,

Option C: -0.5 is the right answer

Find he result when 5m+2 is subtracted from 9

Fudgin [204]

-9 (5m+2) = 0
-45m - 18 = 0
+18 +18
-45m = 18
-45m/-45 = 18/-45
m= 0.4

X+2y=2 …(1)
x-2y=-2…(2)

(1)-(2): (x+2y)-(x-2y)=2- (-2)
4y=4
y=1

subs y=1 into(1)
x+2(1) =2
x=0

so x =0 y=1
the answer is C
