Let's call our unknown angle x .
We know that the sum of the three interior angles of a triangle is 180°
This way,

We get that the third angle measures 29°
Answer:
a = 15/4
Step-by-step explanation:
tan 60 = y/a
√3 = y/a
y = √3a
tan 30 = y/b
1/√3 = y / b
y = b/√3
√3 a = b/√3
3a = b
a+b = 15
a + 3a = 15
4a = 15
a = 15 / 4
Answer:
63 degrees
Step-by-step explanation:
It is an opposite angle so it the same angle
Two lines that are parallel to each other, will have the same slope.
so if this line is parallel to another with a slope of -5/8, the slope of this line is also -5/8 then. We also know that it passes through -7, 4 and -23, y, let's do some checking.
Answer:
7
Step-by-step explanation:
2*6 is 12
12/2 is 6
6+1= 7
