Given there are 12 inches in 1 foot, get rid of how many feet tall she is first. Olivia's 4 ft. 10 in., so we'll multiply 2.54 by 12 and then by 4. We get 121.92. Now we need to add in 10 more inches, so multiply 2.54 by 10, and we get 25.4. Add the two answers together to get Olivia's total height in cm, which is
147.32 cm.
Now for Susan, who's 15 in shorter, we can find her height much easier. Multiply 15 by 2.54. We get 38.1, now we must subtract that from Olivia's total height to get Susan's total height, which will be 109.22 cm.
Hope this helps! Study hard.

Sin θ = 2 / 7
tan θ > 0
cos θ = ?
sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse
short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?
adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5
cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7
Answer:
3
Step-by-step explanation:
hey so we need to make the equations equal to one another for it to have infinitely many solutions
1)distribute the 3
3x+3=3x+_
looking at this we can concur that the missing number is 3. You can check by plugging in the 3 into the equation.
so
3x+3=3x+3
this is true, so 3 is the answer
hope this helps!
