Answer: Angle 2 = 127 degrees, Angle7 = 127 degrees, Angle 8 = 53 degrees
Step-by-step explanation:
Angle 2 = 127 degrees because it is supplementary to 53 degrees.
Angle 7 = 127 degrees because it is alternate exterior to angle 2.
Angle 8= 53 degrees because it is supplementary to angle 7.
Answer:
160
Step-by-step explanation:
one of the triangle faces:
4 × 6 = 24cm^2
theres 4 triangle faces so 24 × 4 = 96 cm^2
then u have to add on the square face which is 8×8 =64cm^2
total:
64 + 96 = 160cm^2
So the proportion would go as follows
5.5. 7.5
=
4.5. 60
To solve this you just cross muliply and divide.
I hope this helps you
Answer:
-6
Step-by-step explanation:
f(x) = 2x + 8
Put x as -7.
f(-7) = 2(-7) + 8
Multiply first.
f(-7) = -14 + 8
Add.
f(-7) = -6
£15
If you add the two ratios together you get 10. Which means that the £50 is made up of 10 pieces. To get Doras amount you have to divide 50 by 10 which is five, and then times the number by how many pieces Dora has, which would be 5x3=15
