Answer:
64
Step-by-step explanation:
The interior angle of a circle has the theorem divide in 2 the sum of the arcs on the circle.
The circle has arcs 42 and 86.
The interior angle is 42 + 86 = 128.
128/2 = 64
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.

Answer:
The required equation is 5x - 3 = 12
Step-by-step explanation:
We have to find the equation for the given condition
Let the number be x as given in the equation
Now according to the condition
5 time the Number is 5 *x = 5x
Three less then 5 time the Number would be 5x - 3
And all of it is equal to 12
Which gives us the equation
5x - 3 =12
The required equation is <em>5x - 3 = 12</em>
