As decimals lets look at them:)
7/8 = 0.875
3/4 = 0.75
In this case 7/8 is actually bigger.

The angle formed by the intersection of two secants outside the circle equals half the difference of the <span>intercepted arcs:
</span>m∠CAE = (124-16)/2 = 108/2 = 54°
Answer is A.
Answer:
- Question 1: x=55
- Question 2: m∠A=45°
Step-by-step explanation:
<u>Question #1</u>
- Since it is an isosceles triangle, this means that the base angles have the same value.
- The angle sum is 180°
Solve
2x+35+35=180
2x+70=180
2x=110
x=55
<u>Question #2</u>
- Since it is given there is a right angle, this means the angle is 90°
- The angle sum is 180°
Solve
5x+5x+90=180
10x+90=180
10x=90
x=9
It asked to find m∠A, which is 5x. So 5x=5(9)=45°
Hope this helps!! :)

Answer:
y = 5 -x
6x +3(5 -x) = 27
Step-by-step explanation:
The first equation is conveniently solved for either x or y. If we solve it for y, we get ...
y = 5 - x . . . . . . subtract x from both sides
This expression for y can be substituted into the second equation to give ...
6x +3(5 -x) = 27
These are your new system of equations.
Simplified, they are ...
_____
The second is a 2-step equation that gives the value of x, which can then be used in the first equation to find y.
3x = 12 . . . . subtract 15
x = 4 . . . . . . divide by 3
y = 5 -4 = 1 . . . . substitute into the first equation
The solution is (x, y) = (4, 1).
