HELP IM SO CONFUSED about this

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

astronomers is your final answer! : )

answer: 1 + 1 = 11
