at noon, shadow of a flagpole is 19 feet long. At same time, shadow is a 12 foot high wall is 4 feet long. what is the height of the flagpole?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
