Sin A 4/5.<br><br> Find<br> COSA + tan A
Ivahew [28]

Answer:

Step-by-step explanation:

The opposite side (the one not connected to A) = 4

The hypotenuse is 5

The adjacent side needs to be found for the cosine and the tangent.

a^2 + b^2 = c^2

a = opposite side = 4

b = adjacent side = ?

c = hypotenuse = 5

4^2 + x^2 = 5^2

16 + x^2 = 25          

x^2 = 25 - 16

x^2 = 9

x = sqrt(9)

x = 3

cos(A) = adjacent / hypotenuse = 3/5

Tan(A) = opposite / adjacent = 4/3

cos(A) + tan(A) = 3/5 + 4/3

cos(A) + tan(A) = 9/15 + 20/15 = 29/15

Triangle J K L is similar to triangle P Q R ..
drek231 [11]

Answer:

t = 7.5

Step-by-step explanation:

PQ and JK are corresponding sides.

QR and KL are corresponding sides.

\dfrac{PQ}{JK} = \dfrac{QR}{KL}

\dfrac{25}{5} = \dfrac{t}{1.5}

5t = 25 \times 1.5

t = 5 \times 1.5

t = 7.5
