Answer:
Therefore first number is 3 and second number is 18
Step-by-step explanation:
Sum of the two numbers is 21 and Second number is six times the first number
x+6x = 21
7x = 21
x = 21/7
x = 3
substitute x value in 6x to find second number,
= 6x
= 6*3
= 18
5x=25
Because negative 3y and positive 3y got cancelled
angle for triangle is 180°
angle ACB is 75° because it has mention that is an isosceles triangle
So that angle of BAC is 180°-75°-75°=30°
First, add in the parentheses. a+3a=4a. Then, make subtraction into adding negatives. (-c)+5c +(-3a)+4a. It becomes 4c+a.
