Okay so form a right angle triangle and the angle of that is 65 as it is right angle so 90 - 25= 65. label the sides like the pic below. 

we have the hypothenuse as well as the angle and we are trying to find the o(opposite side) 

o/h =sin
sin 65=23/h
sin 65 = 23/x
23/sin 65=x 
x=25.4
how high the kite is above ground is :
= 25.4 +1.2
 =26.6

I will give brainiest to whoever answers correctly !!
IgorC [24]

Answer:

Interest rate, R = 244%

Step-by-step explanation:

Given the following data;

Principal = $270

Simple interest = future amount - principal = 309.60 - 270 = $39.60

Time = 22/360 = 0.06 years

To find the interest rate?

Mathematically, simple interest is calculated using this formula;

S.I = \frac {PRT}{100}

Where;

  • S.I is simple interest.
  • P is the principal.
  • R is the interest rate.
  • T is the time.

Substituting into the equation, we have;

39.60 = \frac {270*R*0.06}{100}

Cross-multiplying, we have;

39.6 * 100 = 16.2*R

3960 = 16.2R

R = \frac {3960}{16.2}

<em>Interest rate, R = 244.44 ≈ 244%</em>

<em>Therefore, the pawnbroker charged Elisa a simple interest rate of 244%.</em>

What would the graph of 10x + 7y &lt; 49 look ?
navik [9.2K]

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

10x+7y

2. The equation of the line in slope intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

y=-\frac{10}{7}x+7

then:

m=-\frac{10}{7}\\\\b=7

4. Find the x-intercept. Make y=0. Then:

0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.
