Answer:
B. Acute
Step-by-step explanation:
the hypotenuse for right triangles and lies outside the triangle for obtuse triangles. The circumcenter coincides with the midpoint of the hypotenuse if it is an isosceles right triangle.
Angle a =40° beacuse they are vertical angle
b will be 180- 40+90=50°
c is making supplementry angle with 65 so c+65=180
c=115°
Answer:
2.75
Step-by-step explanation:
55-11(4)=2.75
2.75+11=13.75
13.75x4=55
For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
Answer:
Step-by-step explanation:
All you do is draw a line straight across 5x and then graph 1 which is right next to 5.
