Answer:
correct choice is 1st option
Step-by-step explanation:
Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.
Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Thus, given triangles are congruent by SSS theorem.
By definition you have that the tangent of an angle in a right triangle is given by the quotient between the sine of the angle and the cosine of the angle.
Since we know how much the sine and the cosine measure (we have the sides of the triangles as data), then the tangent is given by:
A. tan Y= y/z
answer
A. tan Y= y/z
5% of 9,500 is 475 so you would add them together. 9,500 + 475 = 9,975 so 9,975 is the answer
3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75
Answer:
-9 1/5 - 10 + 2/5 + 2(14 1/2 - 7) = -3.8
