Answer:
63 girls.
Step-by-step explanation:
45 boys divided by 5= 9
9x7= 63 girls
I think to number you can add to get -34 are -14 and -20
Answer:
x = 10.58
Step-by-step explanation:
It seems the equation is following
3 and 2 will simpy multiply and become 6
will go to RHS and will multiply with 19
6(x+6) will become = 6x + 36
6x = 42.48 + 21
6x = 63.48
x = 10.58
The angle x and 70 are alternate interior so that means they measure the same.
In an isoceles triangle the base angles are the same so that means that both the x angles are 70.
Now we can subtract their sum by 180 to find the measure of angle 1.
180 - (70 + 70) = 40
So the measure of angle 1 is 40.
Hope this helps :)<span />
