Her house is at (-4, 9). Her school is at (-4, 3). The community center is at (1, 3). The grocery store is at (-4, -8). Part A: Use absolute values to calculate the distance in units from Maria's house to her school show your work.

i belive those are the ones that are under 90 degreese.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
