Answer:
∠y=60°
Step-by-step explanation:
Question says to find the measure of the angle Y.
We have been given a picture of triangle XYZ. All angles are marked with same sign so that indicates that all three angles are equal.
∠x = ∠y = ∠z...(i)
We know that sum of all three angles of the triangle is always 180°.
So we can write:
∠x+∠y+∠z=180°
∠y+∠y+∠y=180° {using equation (i) }
3∠y=180°
divide both side by 3
∠y=60°
Hence final answer is the measure of angle y is 60 degree.
Answer:
There will be No solution for the equation
. Option B is correct.
Step-by-step explanation:
We need to determine how many solutions the equation
have.
Solving the equation and finding the solutions

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

Simplifying

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation
. Option B is correct.
Pt=6.245cm, working shown in photo
Answer: His average speed is 8 miles an hour
Step-by-step explanation: First, two halves make a whole, so we simply multiply how many miles he ran in half an hour by 2!
4 x 2 = 8
