Let see...

So we know that × is less than 14.3 subtract by 9.

We can figure out what × is is by subtracting 14.3 with 9 and then find the answer less than it.

$14.3-9=5.3$

So now we know that the answer can be 5.3 or more. This means that we can cross out 5.3, 6.4, and 7.5.

So it would be 3.1 and 4.2.

In AQRS, the measure of _S=90°, QS = 11, SR = 60, and RQ = 61. What is the value

sp2606 [1]

Answer:

0.98

Step-by-step explanation:

sinR = opposite/hypotenuse

sinR = QS/QR

sinR = 60/61

sinR = 0.9836065574

A parallelogram has adjacent sides 25 cm and 6 cm . if one diagonal is 29 cm then find area , height corresponding to the sides

baherus [9]

Answer:

height = 4.8 cm

area = 120 cm²

perimeter = 62 cm

Step-by-step explanation:

<u>**Please refer to the attached diagram when following the step-by-step**</u>

First, find m∠C (green angle on diagram) by using the cosine rule:

$c^2=a^2+b^2-2abcos(C)$

$\implies 29^2=6^2+25^2-2(6)(25)cos(C)$

$\implies cos(C)= \frac{29^2-6^2-25^2}{-2(6)(25)}$

$\implies cos(C)= \frac{180}{-300}=-\frac{3}{5}$

$\implies cos(C)=126.8698976... \textdegree$

Therefore, the interior angle of the right triangle at point C (blue angle on diagram) is:

$180-cos^{-1}(-\frac{3}{5})=53.13010235... \textdegree$

Now use the Sine Rule (for finding sides) to determine height (h):

$\frac{6}{sin(90)}=\frac{h}{sin(53.13..)}$

$\implies \frac{6}{1}=\frac{h}{\frac{4}{5}}$

$\implies 6 \times \frac{4}{5}=h$

$\implies h=\frac{24}{5}=4.8$

So the height = 4.8 cm

Now we have determined the height, we can calculate the area by using the area of a parallelogram formula:

Area of a parallelogram = base x perpendicular height

⇒ area = 25 x 4.8 = 120 cm²

Parallelogram is a four-sided shape made up of two pairs of straight parallel lines that are equal in length.

Perimeter = sum of the sides

⇒ perimeter = 6 + 6 + 25 + 25 = 62 cm

iren2701 [21]

Answer:

y=4/3x-4

Step-by-step explanation:

put a point at 3 on x axis and -4 on y axis. then draw a line connecting then and you can see it goes up 4 and over 3 and it his the y intercept at -4
