Answer:
- there is no M in the diagram
- 145°
- 325°
- 104°
Step-by-step explanation:
EG and IF are assumed to be diameters of the circle. The measures of the two arcs created by a diameter are 180°.
1. There is no M
__
2. arc EF = arc EG -arc FG = 180° -35°
arc EF = 145°
__
3. Angle EDI is a vertical angle to angle FDG, so has the same measure: 35°. Long arc EGI will be 360° minus the measure arc EI
arc EGI = 360° -arc EI = 360° -35°
arc EGI = 325°
__
4. Arc Gi is double the measure of arc GH, so is 38°×2 = 76°. Arc EI is the supplement to this:
arc EI = 180° -arc GI = 180° -76°
arc EI = 104°

Answer:
53°
Step-by-step explanation:
The names of the triangles indicate that angle B corresponds to angle Y. Translation does not affect side lengths or angle measures, so <em>angle Y is the same measure as angle B</em>.
m∠Y = 53°
Make them equal to each other to find their intersection since both equal y
-1/2x+4=y=3/2x
-1/2x+4=3/2x
add 1/2x both sides
4=4/2x
4=2x
divide by 2
2=x
sub back
y=3/2x
y=3/2(2)
y=3
(2,3) is the solution or intersection point
