are allowed to use social media. How many of the students have a cell phone and can use social media?
There are two up there
The little lines inside the two angles mean they are the same.
The 3 inside angles of a triangle equal 180 degrees.
One angle is 146 , so the other two need to equal 180-146 = 34 total.
34/ 2 = 17
Both angle 1 and angle 2 are 17 degrees each.
Answer:
Option A 
Step-by-step explanation:
we know that
The perimeter of the rectangle is equal to
we have
-----> equation A
substitute the value of L in the equation A
Find the perimeter
Acute means that has 3 angles less than 90 degrees
obtuse means at lesat 1 angle is more than 90 degrees
right triangle means 1 angle=90 degrees
s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90
obtuse angle is answer
