A level is set up on a planar slope. The backsight reading on point A is 1.56 feet at a horizontal distance of 200.00 feet. The foresight reading on point B at an equal distance is 12.67 feet. What is the grade of the slope in percent to the nearest 0.01%

step-by-step explanation:

where is the questions

21

jk it's 20

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
