Answer:
x=24°
The triangle is an obtuse isosceles triangle
Step-by-step explanation:
This is an obtuse isosceles triangle because it has two congruent sides, making it an isosceles triangle, and there is an obtuse angle, which is any angle greater than 90°.
The interior angles of a triangle add up to 180, so let's make an equation.
132+2x=180
Then solve for x
subtract 132 from both sides
2x=48
Divide by 2 on both sides
x=24
It would have to be 5 60/100
(5 wholes and sixty out of a hundred)
Answer:
Carlos is 8 , his brother is 9
Step-by-step explanation:
2x + y =25
x= 8
y= 25-16= 9
3 times (2) gives 3x +9y = -21 (3)
<span>(3) - (1) gives 13y = -39 </span>
<span>y = -3 </span>
<span>Sub. y=-3 into (2) </span>
<span>x + -9 = -7 </span>
<span>x = 2
</span>
<span>Answer = (2,-3) </span>
