Answer:
x = 44
Step-by-step explanation:
3x - 5 is complementary to y° so their sum is 180°
The angle with measure 127° is also complementary with y°
127 + y = 180
y = 53°
53 + 3x - 5 = 180
3x + 48 = 180
3x = 132
x = 44
Answer:
B
Step-by-step explanation:
Trust me I got it right and you should too
Hey,
We can see here 2 of the angles are equal and the third one is a right angle right?
That means it is an isosceles triangle since they have 2 equel angles and a right anlgle.
Another feature of the isosceles triangle is that 2 sides are equal.
We are given one side is 5.5 right?
So the side BC has to be 5.5 or the side AB has to be 5.5
In isosceles triangles the side opposite to the 90 degree angle is the hypotenuse.This means it is the longest angle.
So it has to be AB which is equal to 5.5 since BC is the hypotenuse.
Hope this helps,Happy New Year
