Answer:
Angle A = 75°
Angle B = 75°
Angle C = 30°
Explanation:
If AC is congruent to CB, from figure given we have angle A = angle B.
Angle A = 3x + 18
Angle B = 7x - 58
Angle C = 2x - 8
We have,
3x + 18 = 7x - 58
4x = 76
x = 19
So,
Angle A = 3*19 + 18 = 75°
Angle B = 7*19 - 58 = 75°
Angle C = 2*19 - 8 = 30°
Answer:
Value of x = 400
Step-by-step explanation:
Joint variation states that describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them.
Given: x varies directly with y and z.
i.e and
then we have the joint variation as;
......[1] where k is the constant variation.
Substitute the value of x =1200 when y =20 and z = 30 to solve for k;
Simplify:
Divide both sides by 600 we get;
Now, substitute k =2 , y =10 and z = 20 to find x;
Using [1] we have;
Therefore, the value of x is, 400
