Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7
)^2
Add the left side
2x^2= 7^2 + ^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7
Answer:
y – 8 = –0.2(x + 10)
Step-by-step explanation:
Answer:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
Step-by-step explanation:
The size of the angle is always corresponding to the opposite side to it, for example
∠A corresponds to side BC
∠C corresponds to side AB
∠B corresponds to side AC
thus given x=6 then:
AC=x^2-x/2=33
AB=x^2+x/2=39
BC=x^2+x/3=34
thus the order of angles from the smallest to the largest is ∠B, ∠A, ∠C
