Answer:
hello,
Step-by-step explanation:
a)
In an isocele triangle, base's angles have the measure:
42+2a=180
2a=180-42
a=69(°)
b)
in a triangle, an external angle has for measure the sum of the angles not adjacents.
55+b=132
b=77 (°)
c)
in a quadrilater the sum of the (interior) angles is 2*180=360 degrees.
90+90+68+c=360
c=360-90-90-68
c=112 (°)
(-19,7) (4, 15) hshw wjwhw
The answer is 30 I’m sure of it
Answer:
50 each base angle
Base Angle_1 + Base Angle_2 + Vertex = 180
50 + 50 + 80 = 180
180 = 180
Step-by-step explanation:
Sum of interior angles of Triangle is 18- degrees.
2b + vertex = 180
2b + 80 = 180
2b + 80 -80 = 180 - 80
2b = 100
b = 50
Answer & Step-by-step explanation:
Since we use 5 parts blue and 3 parts red, the total sections is 8.
28/8 = 3.5
We want to find the red which is 3 parts.
3.5 * 3 = 10.5.
Your answer should be 10.5 pints of red.
Hope this helps!
