This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.
It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .
And the formula of circumference is

Substituting the value of C, we will get

When the diameter increased by 3, then the circumference is

And the circumference , when diameter is increased by 3 is 29 inches .

Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so

Find the measure of angle BAC
In the right triangle ABC

substitute given value


Find the measure of angle BAD


Find the measure of minor arc BD
we know that
-----> by central angle
therefore

Answer:
bottom graph of left picture
Step-by-step explanation:
For each day he makes his bed, he earns $0.50
In 1 day he earns $0.50
In 2 days he earns $1.00
In 3 days, he earns $1.50
...
In 8 days, he earns $4.00
Look in the 4 graphs.
Which graph has the following points, (1, 0.5), (2, 1), 3, 1.5), ... , (8, 4)?
It is the second graph (bottom graph of left picture.)
