Answer:
125.141
Step-by-step explanation:
Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.
17 is our hypotenuse
17/2 = 8.5, this is one of our legs
The other leg is our height, which we will find.
We use Pythagoras Theorem to find the height/leg: 
= 14.72243186
Now, we use another formula to find the area of the triangle: 
14.72243186 × 17 = 250.2813416
250.2813416 ÷ 2 = <u>125.1406708</u>
Answer:
9 and 4/5
Step-by-step explanation:
Answer:
14 square units
Step-by-step explanation:
If you graph the points your triangle's height will be 4, and base would be 7.
<em>A = 1/2bh 4</em> x 7 = 28, 28 x 1/2 = 14.
Hope this helps :D
Answer:
x = 12.48
y = 13.22
Step-by-step explanation
Im not sure if its correct
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = √156
b = 12.48
b= 12 ( If needed to round to the nearest whole number)
a^2 + 15^2 = 20^2
a^2 + 225 = 400
a^2 = √175
a = 13.22
a = 13 ( If needed to round to nearest whole number)
Answer:
the height is 7.5
Step-by-step explanation:
30 divided by 4 = 7.5
