Y=18.
All triangles are 180 degrees. The given angle is 108 degrees. 180 - 108 = 72. 72 degrees are left to solve for in the triangle. 72 degrees / the two angles = 36. The angles of the triangle are 108, 36, 36. The 36 degree angle = 2y. 36 / 2 = 18.
Y=18
Answer:
well that is a pretty good deal i might have to go there
Step-by-step explanation:
Perimeter of rectangles: 2(L+w)=2(3m+4m)=14m=14*100=1400cm
spider can walk 19cm each second.it can walk perimeter of room in 1400/19=73.6 seconds
15.5 is rounded to the nearest tenth. If you're looking for which number is closest to a whole number then it would be 16 since 5 is always rounded up. Hope this helped :)
Answer:
x = 32, y = 51
Step-by-step explanation:
You know the longest side of ΔTUS is 13m and the longest side of ΔMNP is (2x-y). Thus:
2x - y = 13 --- Equation 1
You know the sum of angles in a triangle is 360°. Two of the angles are given in ΔMNP (142° & 24°) and the remaining angle is (2x-50)°. Thus:
142 + 24 + 2x - 50 = 180
2x + 116 = 180
2x = 180 - 116
2x = 64
x = 64 ÷ 2
x = 32 --- Equation 2
Substitute x = 32 into Equation 1:
2(32) - y = 13
64 - y = 13
-y = 13 - 64
= -51
y = 51 --- Equation 3
