<span>I am replacing θ with A, so don't get confused
</span>
csc^{2} A-4=0

csc^{2} A- 2^{2} =0

(cscA+2)(cscA-2)=0

Using zero product property:
EITHER
cscA+2=0
cscA=-2
A = -30°

OR
cscA-2=0
cscA=2
A=30°

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER

Answer:

B. 5x - 4y = 12

Step-by-step explanation:

Let's convert this to slope-intercept form to interpret the equation easier.

5x - 4y = 12

Subtract 5x from both sides.

-4y = -5x + 12

Divide both sides by -4.

y = 5/4x - 3

Based on this, we know the slope is 5/4 and the y-intercept is (0, -3). When you count the rise over run in the picture and look at the y-intercept, they match.

What is the value of 324 + 435 + 546 when written in base 7?
Arada [10]
<span>The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.</span>
