Vertically opposite angles are equal
With this information we can form an equation
2x+14=60
Subtract 14 from both sides
2x=46
Divide both sides by 2
X=23
x = 23 degrees
1.They basically all did one big bug,not separate hugs with different bears.
Step-by-step explanation:
I dont remember perimeter but area is A= 1/2 bh
Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is

Answer:
y=90 degree
Step-by-step explanation:
bcz this triangle is drawn in the semi-circle and the greatest angle of triangle in a semi-circle is always right angle.
