Answer:

2.30

Step-by-step explanation:

The side of interest is opposite the given angle, and the hypotenuse is given. The sine relation tells you ...

sin(A) = a/c

a = c·sin(A) = 3·sin(50°)

a = BC ≈ 2.2981 ≈ 2.30

45 Points, Question 2 In Attachment. Asap if possible.

Masja [62]

Answer: x = $\frac{-5}{2}$

Step-by-step explanation:

$3^{4x-5}$ = $(\frac{1}{27}) ^{2x+10}$

1/27 can be written in index form as $3^{-3}$

The equation then becomes:

$3^{4x-5}$ = $(3^{-3})^{2x+10}$

Equating the coefficient

4x - 5 = -3 ( 2x + 10)

4x - 5 = -6x - 30

10x = -30 + 5

10x = -25

x = -25/10

x = -5/2

x = - 2.5

What is the length of if ? 8 in. 8.75 in. 10.25 in. 14 in.

quester [9]

Answer:

Diagram attached

AJ = 8.75 in.

Step-by-step explanation:

Since triangles HBA & HKJ are similar,

BH/AH = KH/JH

3 in /5.25 in = 8 in /JH

JH = 14 in

JA = JH - AH = JH - 5.25 in = 8.75 in

HJ = 14 in.

AJ = 14 in - 5.25 in

AJ = 8.75 in.

Find the values of X and Y.

Natasha_Volkova [10]

Answer:

x = 90°

y = 43°

Step-by-step explanation:

We know that one angle equals 47°.

The two triangles are right triangles, so that makes x = 90°.

To find y, we add 90 + 47.

That would give us 137°.

All triangles add up to 180°.

180 - 137 = 43.

43° is the answer.
