Answer:
60
The angle acute so my guess is 60
Hope this helps :)
Your answer should be the last one!!
The equation which related the three sides of the shown triangle is:
a^2=b^2 + c^2 where a is the longest side and b & c are the other two sides.
the only values satisfy the above equation is:
a=17, b=8 and c=15
17^2=8^2+15^2
289=64+225

Answer:
1) area = (x + 3)(2x + 3) ft²
2) 299 ft²
Step-by-step explanation:
<u>Question 1</u>
Area of a rectangle = width x length
Given:
- width = x + 3
- length = 2x + 3
⇒ area = (x + 3)(2x + 3) ft²
<u>Question 2</u>
If x = 10:
⇒ area = (10 + 3)(2(10) + 3)
= 13 · 23
= 299 ft²
