Answer:
x = 17
∠A = 114°
Step-by-step explanation:
In the figure attached, the complete question is shown.
From the figure, we know that:
∠A = ∠B
Replacing with the expressions, we get:
6x+12 = 3x+63
6x - 3x = 63 - 12
3x = 51
x = 51/3
x = 17
∠A = 6(17)+12
∠A = 114°
Answer:
Triangle BCA and Triangle KIJ are congruent by SAS rule
We can divide 15 by 4. This gives us 3.75. This means that each pizza costs $3.75. I can now multiply 3.75 by 5.
3.75(5) = 18.75
5 pizzas cost $18.75.
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet
Answer:
B -- scalene acute triangle
Step-by-step explanation:
None of the measures are >90 degrees. All of the lengths and angles are different sizes. This means that the triangle is an acute scalene triangle
