Answer:
x = 15, y = 38
Step-by-step explanation:
2sides of the triangle are congruent, thus triangle is isosceles.
The 2 base angles are therefore congruent and since right isosceles triangle
Then each base angle = 45°, then
3x = 45 ( divide both sides by 3 )
x = 15
and
y + 7 = 45 ( subtract 7 from both sides )
y = 38
Answer:
True, True, False.
Step-by-step explanation:
A) Rise/Run is 8/1

C) Correct equation is y=8x
Answer:
Choose c if only one answer
If you can choose 2, then choose a and c
Step-by-step explanation:
sqrt (-80)
±sqrt(-1) * sqrt(80)
sqrt(-1) = i
±i sqrt(80)
±i sqrt(16) *sqrt(5)
± 4i sqrt(5)
The principal square root is 4i sqrt(5), but -4i sqrt(5) is also true
Given: to simplify
X=sqrt(30)-2sqrt(32)
factor:
X=sqrt(2)sqrt(15)-2sqrt(2)sqrt(16)
=sqrt(2)(sqrt(15)-2*4)
=sqrt(2)(sqrt(15)-8)
alternatively, we can also put
X=sqrt(30)-8sqrt(2)
