Your right it’s an obtuse angle
Answer:
The correct answer is B
Step-by-step explanation:
2(x-1) + 5x = x-8
Firstly, break all the brackets and you would got:
2x - 2 + 5x = x - 8
Put x into 1 side,
2x + 5x - x = -8 + 2
6x = -6
Divide both side by 6,
6x / 6 = -6/6
x = -1
The correct answer is B

Answer:
90 degrees
Step-by-step explanation:
All trapazoids are equal to 360 degrees.
so we can make an equation 2x+x+x=360 (the other corner would also be x because its an unknown value)
to simplify, 4x=360
you divide into both sides (360/4)
you get 90

Answer:
44
Step-by-step explanation:
The formula to find to area of a circle is
= Area
The perimiter formula is
= Perimeter
Since we know the area (154cm) we can find the radius (r) with the formula.
You first have to find what the radius of the circle is with.

= 154
3.14
=154
Now simplify.
=49 (rounded)
r=7
Now we can find the perimeter with the formula above.
= P
Now plug in.
2(3.14)(7)= P
44=P (Rounded)
