Answer:
a)29
b)70
Step-by-step explanation:
The sum of the interior angles in a triangle is 180.
a)95+56+a=180 b)40+2b=180
151+a=180 2b=180-40
a=180-151 2b=140 /2
a=29 b=70

Answer:
z = - 170
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 19
m = 
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (- 6, z)
m = 
= 
= 19 ( multiply both sides by - 9 )
z- 1 = - 171 ( add 1 to both sides )
z = - 170
Answer:
a) y = 7
b) y =5 sin t
Step-by-step explanation:
Answer:
<1 =33
<2 = 147
<4 = 147
Step-by-step explanation:
Angle 1 equals angle 3 because they are vertical angles. Vertical angles are opposite angles made by two intersecting lines.
<1 = <3
<1 = 33
Angle 2 and <3 are supplementary angles because they form a straight line. The add to 180 degrees
<2 + <3 = 180
<2 + 33 = 180
Subtract 33 from each side
<2 +33-33 = 180-33
<2 = 147
Angle 2 equals angle 4 because they are vertical angles
<2 = <4
<4 = 147
