Answer:
b = 16.5
Step-by-step explanation:
Given
=
( cross- multiply )
9b = 148.5 ( divide both sides by 9 )
b = 16.5
Answer:
141 °
since they are supplementary angles and they always add to 180 °
24,10,26. Basically if you multiply each of the sides by the same number, (I multiplied everything by 2) then that will keep the ratios the same. You should be able to multiply each side by any number, but two will usually be the easiest
Answer:
24 and 21
Step-by-step explanation:
the ratio of their ages is 8 : 7 = 8x : 7x ( x is a multiplier )
In 6 years
8x + 6 : 7x + 6 = 10 : 9
Express the ratio in fractional form
=
( cross- multiply )
9(8x + 6) = 10(7x + 6) ← distribute parenthesis on both sides
72x + 54 = 70x + 60 ( subtract 70x from both sides )
2x + 54 = 60 ( subtract 54 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
Tony = 8x = 8 × 3 = 24
Vihaan = 7x = 7 × 3 = 21
Angles are named with 3 letters with the vertex listed in the center to go from angle to arc name take the first and last letter from the angle to name it.
For arc to angle insert the letter of the center in between the listed arc endpoints.
Ex1: Angle ABC is are AC
Ex2: Arc DF with center X is angle DXF
