Answer:

m∠B = 107°

Step-by-step explanation:

Since we know that all angles in a triangle add up to 180°, we have

m∠D = 180 - (32 + 41) = 107°

Since we also know by the given picture that both triangles are congruent, we know that the m∠D is equal to m∠B, so m∠B = 107°

The perimeter of a rectangular plot is 300 m. Its width is 52 m.<br> What is its area?
madreJ [45]
5’096 m
If one side of the rectangle is 52m then you can assume that both sides would equal 104m. That leaves the other 2 sides to equal 196, and that means that one of the other sides would equal 98. The equation to find area is length x hight, so you’re gonna do 52 x 98 giving you 5’096. :) hope that helps!!

Help help help!!!!!!!!
Dmitriy789 [7]
For y=2x+125, the slope is 2, which means that the total will increase by 2, and the y-intercept is 125, and that is the starting value. So, y=2x+125 goes with the second choice on the right. For y=1/2x+125 means that 125 is still the starting value but instead of the total amount increasing by 2, it is divided by 2 and goes with the first choice on the right. For y=125x+2, the slope is 125 and 2 is the y-intercept, so the answer is the last one on the right.
