Answer:
45 is the answer
Step-by-step explanation:
first you have to know the sum of interior angle of that pentagon (540)
then add the all angle.
148 + x + 112 + 90 + 3x + 10 = 540.
or, 360 + 4x = 540
or, 4x = 540 - 360
or, 4x = 180
or, x = 180/4
or, x = 45
hope it will help you☺✌
Answer:
15 and 17 are both undefined, 16 the slope is 0
Step-by-step explanation:
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
Answer:
B
Step-by-step explanation:
e is the base of the natural log system.
take the natural log of both sides.
ln(e^a) = ln(60) The power can come down
a ln(e) = ln(60) The natural log of e = 1
a * 1 = ln (60)
a = ln(60)
the sum of the angles in a triangle = 180°, thus
x + 
x + 
x = 180
multiply through by 6
6x + 3x + x = 1080
10x = 1080 ( divide both sides by 10 )
x = 108
the angles are 108°, 54° and 18°
Since all the angles are different and the largest is 108°
The triangle is an obtuse scalene triangle
