ANSWER:
d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3
Sorry if I explained it too thoroughly but I’ll be glad to answer any questions or clarifications
Answer:
both of the answers are c
Answer:
x = -3
Step-by-step explanation:
Since they give you the function in binomial factor form, it is very straight forward to find what its zeroes are: Those x-values for which any of the binomial factors renders zero would be a so called "zero" of the function.
We examine each of these binomial factors [ (x+3), (x-7) and (x+5) and notice that for the factor:
(x+3) to be zero, x needs to be equal to "-3",
(x-7) to be zero, , x needs to be equal to "7",
(x+5) to be zero, , x needs to be equal to "-5".
therefore, from the options they give you, only "x= -3" is correct.
Answer:
∠c' and ∠c'' are complementary angles
Step-by-step explanation:
Since form a straight angle, then
then they are supplementary angles.
Since the is perpendicular and bisects ∠C
∠c' and ∠c'' are complementary angles
Answer: 25
Step-by-step explanation:
if she has 120 and if she has 20 leftover that means she used a 100. then u divide 100 by 4 cause it's a square and u get 25
