Answer:
correct choice is 1st option
Step-by-step explanation:
Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.
Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Thus, given triangles are congruent by SSS theorem.
Answer:
x = 6.928
Step-by-step explanation:
Since we don't know the hypotenuse, we will use tan
tanΘ = opposite/adjacent (Θ = theta, which is basically the variable for an angle)
tan30° = x/12
to find x, multiply 12 to the other side
12tan30° = x (plug this into a calculator)
x = 6.928
Answer:
x = 20
ABC = 85

I answered your other question, so basically just read the explanation there cuz I'm too lazy to write it again :P
Answer:
y = |x-3| -1
Step-by-step explanation:
The parent function has been shifted right 3 units and down 1 unit. That is f(x)=|x| has been moved to ...
y = f(x -3) -1
y = |x -3| -1 . . . . matches the last choice
