Answer: 15 cm²
Step-by-step explanation: To find the area of a triangle, start with the formula for the area of a triangle which is shown below.
In this triangle, the base is 6 centimeters and the height is 5 centimeters. Now, plugging into the formula, we have 
.
Now, it doesn't matter which order we multiply.
So we can begin by multiplying 1/2 times 6 cm and notice that the 2 in 1/2 and the 6 cross cancel to 1 and 3. So we're left with 3 cm.
Now, (3 cm)(5cm) is 15 cm².
So the area of the triangle is 15 cm².
Answer:
x=65°
Step-by-step explanation:
All angles in a triangle add up to 180°
So 180-85-33=62°
90-62=28°
180-87-28=65°
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
Answer:
D. He multiplied the divisor by 100 and the dividend by 10.
Step-by-step explanation:
From the question: The following steps are given:
754 divided by 0.52.
754 = Dividend
0.52 = Divisor
Step 1
7540 ÷ 52
This is where he made his error,
He multiplied the divisor by 100 and the dividend by 10.
The correct step would be
To Multiply both the Divisor and the Dividend by 100
= 75400 ÷ 52
Option D is the correct option
