-4(4)=-16
3(1/7)=3/7
I think that’s what you are asking...
X = 61 degrees.
Find the number of degrees in a pentagon by using the following formula:
(number of sides - 2)180 = 540.
There are 540 degrees in a pentagon.
Since we know four of the angles, we can subtract them from 540 to get the fifth angle.
540-138-144-107-90 = 61
Hope this helped =)
Answer: x=-2 y=-8 or (-2,-8)
Step-by-step explanation:
Cos (x) = adj/hyp
cos (x) = 13/25
x = cos⁻¹(13/25)
x= 58.7° (nearest tenth)
D because there sides are congruent
