Área of rectangle= 18 x 14 = 252
Area or triangle=
30-18= 12
12 is the base of the triangle
14 is the height of the triangle
Area of a Triangle= 1/2bh
1/2(12)(14)=84
Área of Triangle= 84
252+84= 336
Answer= 336
I think it's D because you times everything from the left column to the right column
Answer:
Step-by-step explanation:
Convert to a decimal
Step 1. Reduce the fraction to its lowest terms.
Divide both numerator and denominator by their greatest common factor (12)
Step 2. Convert the denominator to a power of 10
Multiply both numerator and denominator by 2.
Step 3. Divide the numerator by the denominator
Dividing by 10 moves the decimal point one place to the left.
Answer:
- angle at A: 51°
- base angles: 64.5°
Step-by-step explanation:
The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.
The base angles at B and C are the complement of half this value, or ...
90° -(51°/2) = 64.5°
The angle measures in the triangle are ...
∠A = 51°
∠B = ∠C = 64.5°
Answer:
a = 12
Step-by-step explanation:
add 2 to each side
5a/3 = a/4 + 17
distribute 12 to remove fractions
20a = 3a + 204
17a = 204
a = 12
