Answer:
180
straight
Step-by-step explanation:
Hello There
So we are given that angle a is equal to 11x + 37
we are also given that x = 13
because we are given the value of x we can simply find the measure of angle A by plugging in 13 to x into the expression
so basically angle A = 11 ( 13 ) + 37
11 * 13 = 143
143 + 37 = 180
now we want to classify the angle
here are the angle types and what they measure
(let x be measure of angle)
acute 0 < x < 90
so an acute angle has a measure of less than 90 degrees
the measure of angle A is 180 degrees so we can clarify that it is not an acute angle
right angle x = 90
a right angle has a measure of 90 degrees
angle a has a measure of 180 degrees therefore it is not a right angle
obtuse angle 90 < x < 180
the measure of an obtuse angle must be less than 180
because angle a = 180 it is not classified as an obtuse angle
straight angle x = 180
the measure of a straight angle is 180 degrees
angle a measure 180 degrees so we can conclude that angle a is a straight angle
