The answer is below
Step-by-step explanation:
a) Triangle A is attached in the image below.
The base of triangle A is 3 units and its height is 3 units. The area of a triangle is given as:
Area = (1/2) × base × height
Area of triangle A = (1/2) × base × height = (1/2) × 3 × 3 = 4.5 unit²
Area of the scaled copy = 72 unit²
Ratio of area = Area of the scaled copy / Area of triangle A = 72 unit² / 4.5 unit² = 16
Hence the scaled copy area is 16 times larger than that of triangle A.
b) For the scaled copy:
Area of the scaled copy = (1/2) × base × height = 72 unit²
base × height = 144
Since the base and height are equal
base² = 144
base = 12, also height = 12
Base of scaled copy = 12 = 4 × base of triangle A
Therefore the scale factor used is 4
The height is represented by d.
d = 10 feet
Use quadratic formula:
t = 1.58, -2.02 (reject)
1.58 seconds
So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.
Combine like terms to get
Subtract 470 on each side to get
Then just divide on each side and you'll get
To find the value of the (x+10) angle, just substitute 125 for x and solve.
