Answer:
The area of the triangle is 10 square units.
Step-by-step explanation:
The formula for area of a triangle is A = bh.
The problem gives us this information:
b = 4 units
h = 5 units
You can use the formula and plug the numbers into the equation to find your answer of 10 square units.
Answer:72
Step-by-step explanation:
Answer: 12 square feet
Step-by-step explanation:
The formula for calculating the area of a triangle is given as :
Area = x base x height
height = 3 feet
base = 8 feet
substituting into the formula , we have :
Area = x 8 x 3
Area = 4 x 3
Area = 12 square feet
Therefore : the area of the sign in square feet = 12
The board A is 8 inches. If you use 3/4 of an 8-foot-board. Then you're left with 2 feet.
3 6
-- = --
4 8
8 - 6 =2
(8= the length of the board)
1/3 of 2 feet = 8 inches
1 24 24
-- x -- = --- = 8 inches
3 1 3
(24= the equal amount of inches in a 2-foot-board)
Answer:
113°
Step-by-step explanation:
By remote interior angle theorem:
a + 35° = a - 30° + a - 48°
a + 35° = 2a - 78°
35° + 78° = 2a - a
113° = a
a = 113°
