Answer:
5
Step-by-step explanation:
Let the number be x
Therefore 3times the number will be 3x
3x + 2= 17
3x =17-2
3x=15
x=15/3
x= 5
The sum of angles inside a triangle is the sum of angles 1, 2 and 3, which form a straight line, therefore 180 degrees.
The sum of the exterior angles
angle exterior angle
1 2+3
2 1+3
3 1+2
total 2+3+1+3+1+2=2(1+2+3)=2(180)=360 degrees.
Step-by-step explanation:
In Figure 5.9 below
ABCD is a parallelogram
with m(∠ABC) = 43o
CD
. A
line through A meets
at E and m(∠AED) = 68o
a. m(∠ADE)
.
Find
b. m(∠ DAE)
c. m(∠BCD)
Y= -1/3x +5
5 is the y-intercept (where the line touches the y-axis) and -1/3 is the slope (rise over run, but since its negative, you go down 1, over 3 to the right) Hope this helps!!!
