Answer:
x = 69°
Step-by-step explanation:
1). JFGHI is a pentagon, every angle in a Pentagon is equal to 108°.
2). angle JIH + angle HIE = 180°; angle JIH = 108, so angle HIE = 72°.
3). angle JDI is equal to 39° and angle IEH; so angle IEH = 39°
4). Now we know 2 out of the three angles in the triangle IHE, so we can find x!
5). x + angle HIE + angle IEH = 180°
x + 72° + 39° = 180°
x = 69°
Answer:-3
Step-by-step explanation:
The total surface area is 20

<span><u><em>Answer:</em></u>
(-2,5)
<u><em>Explanation:</em></u>
<u>We are given the following translation rule:</u>
(x,y) .............> (x-3 , y+4)
<u>This means that:</u>
new x coordinate can be found by subtracting 3 from the old x coordinate
new y coordinate can be found by adding 4 to the old y coordinate
<u>From the figure,</u> we can note that the coordinates of point A are (1,1).
Applying the above translation rule, we can get the coordinates of A' as follows:
x coordinate of A' = x coordinate of A - 3
x coordinate of A' = 1 - 3 = -2
y coordinate of A' = y coordinate of A + 4
y coordinate of A' = 1 + 4 = 5
Based on the above, the coordinates of A' would be (-2,5)
Hope this helps :)</span>
