Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
B i think the answer is for #5
The answer is -4 i just did the test
9y is the answer I believe
The rate is 1km/15min
It's a fraction where the denominator is 15 minutes.
To make it a unit rate, we need to make the denominator 1.
A unit rate would be 4 km / hour.
