Answer:
Area of triangle = 8.9
Area of parallelogram = 53.4 yd² (option A)
Step-by-step explanation:
✔️Area of the triangle = ½*base*height
base = 3 m
height = 5.9 m
Area of triangle = ½*3*5.9
Area of triangle = 8.85 ≈ 8.9 (nearest tenth)
✔️Area of parallelogram = base*height
base = 8.9 yd
height = 6 yd
Area of parallelogram = 8.9*6 = 53.4 yd²
Answer:
Step-by-step explanation:
The translation to a math expression is ...
<em>The sum of a number and 5 is negative 28.</em>
x + 5 = -28
Subtract 5 from both sides of the equation:
x + 5 - 5 = -28 -5
x = -33
The number is negative 33.
The Pythagorean theorem tells you
... (height of ladder)² + (distance from house)² = (length of ladder)²
... (height of ladder)² + (8 ft)² = (12 ft)²
... height of ladder = √(12² - 8²) ft
... height of ladder = √80 ft ≈ 8.94 ft
