1. Maria cannot remember what she scored on the second test but she knows that the sum of the three tests is 270 write and solve an addition equation to determine what she scored on her second test I 88x92=+270​

step-by-step explanation:

f

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

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
