Answer:
B) 10
Step-by-step explanation:
Exterior angle property: Exterior angle equals the sum of opposite interior angles.
12x + 10 = -10 + 7x + 70 {Subtract 10 from both sides}
12x = -10 + 7x + 70 - 10
12x = -10 + 70 - 10 + 7x {Combine like terms}
12x = 50 + 7x {Subtract 7x from both sides}
12x - 7x = 50
5x = 50 {Divide both sides by 5}
x = 50/5
x = 10

Answers
Answer:
a
Step-by-step explanation:
formula for cos theta is ration of adjacent side to hypotenuse side
so, 28 is adjacent side.
and 53 is hypotenuse side.
Thats why the ans is A
The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is A.
What are Trigonometric functions?
The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.
The value of cosθ can be written as,
Cosθ = Base / Hypotenuse
Cosθ = 28/53
Hence, the correct option is A.

b. SAS
Step-by-step explanation:
These triangles can be proven congruent through SAS, or side, angle, side. SAS is used when two sides and one included angle are congruent. For an angle to be included, it must be in between the other two sides. This means the angle's rays are the congruent sides. If two lines have an equal number of tick marks, or if two angles have an equal number of arcs, then they are congruent. In this image, two line pairs are marked as congruent as well as the included angle. Therefore, the correct answer is B. SAS.
