All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°
102+39=141°
180-141=39°
x = 39°
(0.75 * 3.5a) + (0.75 * -6b) = 2.63a -4.5b
Answer:
His error is multiplying by 4 sides as he thought it was total surface not lateral surface area- the final answer is 12
Step-by-step explanation:
He should have multiplied it by 3, because the 3 sides- not including the base- is what lateral surface area is. He originally did total surface area not lateral surface area so each sides area is 4m squared then you just multiply it by 3 and its 12
Answer:
42 plants
Step-by-step explanation:
Dimensions are missing.
Suppose a right triangle has a base of length 7yards and a height of 24 yards.
As you know, Area of triangle can be determined by
Area of triangle 'A'= 1/2 x b x h = 1/2 x 7 x 24
A= 84 yards²
Now she wants 2 plants for each square yard of area
therefore, if the area is 84 yards²:
number of plants are 84/2=> 42 plants
Thus, She wants 42 plants in the garden
