Answer:
No
Step-by-step explanation:
His answer is incorrect. If we round the dimensions, 3.76 m is almost 4 m, and 5.49 m is almost 5.5 m. 4 × 5.5 = 22. So his answer should be close to 22 m².
Answer:
68°
Step-by-step explanation:
Attached is an image of the isosceles triangle theorem.
Utilizing this theorem, we know that the bottom two angles are congruent, or the same.
We also know that there are 180° in a triangle. Lets find x!
1) Write an equation to find angle x:
56+56+x=180
2) Simplify
112+x=180
3) Subtract 112 from both sides:
x=68°
A 10-foot ladder leans against a wall. It hits the wall 9 feet up. How far is the base of the ladder from the wall? Apply the Pythagorean Theorem to this problem
triangle
side S1 = 9 feet
hypotenuse H = 10 feet
side S2 - X = ?
the Pythagorean Theorem
H x H = S1 x S1 + S2 x S2 = S1 x S1 + X x X
X x X = H x H - S1 x S1 = 10 x 10 - 9 x 9 = 100 - 91 = 9
X x X = 9
X = 3
How far is the base of the ladder from the wall? 3 feet
check:
H x H = S1 x S1 + X x X
10 x 10 = 9 x 9 + 3 x 3
100 = 91 +9 = 100
