Answer:
<h2><u><em>
Acute isosceles triangle</em></u></h2>
Step-by-step explanation:
What type of triangle is shown in the image?
A triangle with two sides that are each eight units, and one side that is five units. Two angles are seventy degrees, and one angle is forty degrees.
Acute scalene triangle
Obtuse scalene triangle
<h2><u><em>
Acute isosceles triangle</em></u></h2>
Right isosceles triangle
First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.
m∠O = 2 (65°) = 130°
Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.
m∠O + m∠C + m∠B + m∠A = 360°
Substituting the known values,
130° + 90° + 90° + m∠A = 360°
The value of m∠A is equal to 50°.
<em>Answer: 50°</em>
When you subtract them you get the answer 57.99
