PLEASE HELP GEOMETRY PROBLEMS !!!?
1. Triangle A has a height of 12cm and a base of 15cm. Find the base of triangle B if it has a height of 17cm.
2. A right triangle at Angle A has an opposite side of 13m, and an adjacent side of 15m. Determine the length of the hypotenuse, then find the ratio of sine, corine, and tangent.

1.
Triangle A has a height of 12 cm and a base of 15 cm.
The base of triangle B, if it is similar to Triangle A
and has a height of 17 cm, will be 21 1/4 cm.
2.
A right triangle at Angle A has an opposite side of 13 m,
and an adjacent side of 15 m.
Hence the length of the hypotenuse is 19.849.. m.
The ratio of sine, cosine, and tangent will be
13/19.85, 15/19.85, and 13/15.

as 'alex ' queries are they similar ? and for 2) a² + b² = c² where c = 13 , a = 15...find b....but the given data is not correct for the query...c > a...if the right triangle is at A then opposite is the hypotenuse...so correct your query

1/ Are they similar ?
2/
the hypotenuse = √(a^2 + b^2)=√(13^2+15^2)=...
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
tan = opposite / adjacent
