Find the missing side. Round to the nearest tenth.
Firdavs [7]

Answer: <em>23.7</em>

Step-by-step explanation:

<em>Let's calculate the acute angle at the base of the triangle:</em>

<em>180° - 90° - 40° = 50°</em>

<em>Find side x:</em>

\dfrac{sin \: 90^{o} }{31} =\dfrac{sin \: 50^{o} }{x}\\\\sin \: 90^{o} \cdot x=sin \: 50^{o} \cdot 31\\\\sin \: 90^{o} =1\\sin \: 50^{o} \approx 0.766\\1 \cdot x =0.766 \cdot 31\\x=23.746\\23.746 \approx 23.7

What is the perimeter of the triangle expressed as a polynomial? 3x+4, x-10, 5x-2
Ganezh [65]
Your answer is 9x-8.

3x+4, x-10, 5x-2. If you combine the x's you get 9x. You can combine the numbers however you'd like. I chose to combine +4 and -2. That's 2. 2-10 = -8. Therefore your answer is 9x-8.

a gardener has 8 pounds of fertilizer. He packs the fertilizer into 5/8 pound bags. What is the maximum number of 5/8 pound bags
navik [9.2K]
A gardener has 8 pounds of fertilizer. He packs the fertilizer into 5/8 pound bags. What is the maximum number of 5/8 pound bags he can pack?

so first you multiply 8 pounds times 5 from 5/8 which is 40/8 pounds bags
now how many 8s can fit in 40 
40 divided by 8 =5 
so he can pack 5 maximum bags

Which of the following compositions will map the red figure onto the blue figure?<br> 6lB<br> ATA
melisa1 [442]

Answer:

Point A is translated to A" by T(0, -6), since A has been shifted 6 units down

check the picture, the translated triangle is A"'B"'C"'.

clearly the angle between B"'A"' and B"A"' is 90 degrees, so we can complete the transformation by a 90° clockwise rotation or a 270° counterclockwise rotation.

from the choices given, we see that is is a 270° counterclockwise  rotation.

Answer: A.(o,-6). Ra,270
