Points

1.) kayla wants to find the distance, ab, across a river. she walks along the edge of the river 75 ft and marks point c. then she walks 100 ft further and marks point d. she turns 90° and walks until her final location and marks point e. point e, point a, and point c are collinear.

2.) can kayla conclude that ∆abc and ∆edc are similar? why or why not?

3.) suppose de= 175 ft. what can kayla conclude about ab? explain. don’t forget to label your answer.

1 - yes 100 and 75 are both collinear both are the same line.

2 - She can conclude that there both similar because the both go the same direction and both same shape.

3 - AB would equal 150 because the other one was 100 and the other angle was 25 down. So AB would equal 150.

Hope I helped

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
