This is the same question of isosceles triangles. i need

x = 46

Step-by-step explanation:

Since two sides of the triangle have the same length, we knows it's isosceles. This means we we will have two base angles with the same value, and one vertex angle.  Since 88 is the angle in between both legs, we knows 88 is the vertex angle.  This means x is one of the base angles.

So 2x + 88 = 180

2x = 92

x = 46

addition

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
