Answer:
(40/2)-15
Step-by-step explanation:
We know the triangle is an isosceles triangle. So, we use the Pythagorean Theorem.
a^2+b^2=c^2
The c would be 22, because it's the longest edge. Now find a or b. They are the same, that is how you find the two sides of the triangle for part A.
To find the area of the triangle, the forumla is a=hb/2
Plug in the numbers for that formula and the answer would be found for part B.
I hope I helped.
the answer will be 0.092 as a decimal
Answer:
x=125
Step-by-step explanation:
A 7 sided figure (heptagon) has interior angles equaling 900°. (7-2)x180
900-60-90=750
6x=750
x=750÷6
x=125
Your answer should be x=5
