Answer:
Right and Isosceles
Step-by-step explanation:
Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
Answer:
x>21
Step-by-step explanation:
3x-15>48
Add 15 to each side
3x-15+15>48+15
3x > 63
Divide by 3
3x/3 >63/3
x > 21
Open circle at 21 since there is no equals sign, line to the right
The given equation is:
(8+3a) * a
To get the value at a=1/3, we will substitute the value of a in the given equation with 1/3 and compute the result as follows:
(8+3(1/3)) * (1/3)
(8+1)*(1/3)
(9) * (1/3) = 3
