∠ACE is formed by two secants intersecting outside of a circle. If minor arc BD = 25°, minor arc AB = 115°, and minor arc DE = 1
dmitriy555 [2]

Answer:

m∠ACE = 40°

Step-by-step explanation:

Consider the below figure attached with this question.

Given information: arc BD = 25°, minor arc AB = 115°, and minor arc DE = 115°.

We need to find the measure of ∠ACE.

minor arc AB + minor arc BD + minor arc DE + minor arc AE = 360°

115° + 25° + 115° + minor arc AE = 360°

255° + minor arc AE = 360°

minor arc AE = 360° - 255°

minor arc AE = 105°

The measure of minor arc AE is 105°.

Using Intersecting secants outside the circle theorem

Angle between two secants = \frac{1}{2}(Major arc - Minor arc)

\angle ACE=\frac{1}{2}[Arc(AE)-Arc(BD)]

\angle ACE=\frac{1}{2}[105-25]

\angle ACE=\frac{1}{2}[80]

\angle ACE=40

Therefore, the measure of ∠ACE is 40°.

Help with math homework please
igomit [66]

Answer:

42°

Step-by-step explanation:

8y+2(5y-18)=180

8y+10y-36=180

18y-36=180

18y=216

y=12

Plug y back into the equation for angle O

5(12)-18=42
