Answer:
a=170
Step-by-step explanation:
(a+10)=180[because being a straight line]
or, a+10=180
or,a=180-10
a=170
Therefore,a=170
X=10 let me know if you need the work
Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !
checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance
answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance
answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance
Conclusion : answer A
The answer should be 1/9y^4
Answer:
600.4 cm^2
Step-by-step explanation:
first we should find the base of samller triangle
hypotenuse = 35 cm
one side = 30 cm whereas other has be be find
using pythagoras theorem
a^2 + b^2 = c^2
30^2 + b^2 = 35^2
900 + b^2 = 1225
b^2 = 1225 - 900
b^2 = 325
b = 
b = 
area of big triangle
base = 22 + 
area of a triangle = base * height / 2
= 30 (22 +
) /2
=30*22 + 30*
/ 2
=660 + 540.83 / 2
=1200.83 / 2
=600.415
=600.4 cm^2
