To find the length of the base, you must first find the length of the sides, or the value of x. Because it is an isosceles triangle, the legs are equal to each other.
2x + 4=x + 8
x=4
Now that you have found x, plug it into the equation for the base.
5(4) - 2
20 - 2
18
Final Answer: 18
Hope this helps!! :)
I could only answer 14. and it is 138.3
It's a proportion. Set it up as 3/30 * x/11= 1.1
It can be any angle between 1 and 64 since the third angle has to be a right angle or an obtuse angle
Answer:
S = 5y + 4
Step-by-step explanation:
f is Sara's father, y is Sara, b is Sara's brother and S is sum
3y = f
b = y + 4
S = f + y + b
= 3y + y + y + 4
= 5y + 4
Hope this helps!
