Answer:

I feel like a lot of people try to get people just to do the work for them on this site.

Step-by-step explanation:

To actually find the area of this shape without using a too high level of math, you would split the shapes into geometric shapes and you should find that you have all the values to make that line up. Just remember to be careful. This will take a moment which is why i'm not doing it. Remember area = b*h area of triangle = 1/2*b*h

HELP ASAP TIMED !!!! What is the exact value of cos(c + d), given Sine c = StartFraction 24 Over 25 EndFraction for c in Quadran
Keith_Richards [23]

9514 1404 393

Answer:

  D

Step-by-step explanation:

In the second quadrant, ...

  c = 180° -arcsin(24/25) ≈ 106.26°

In the third quadrant, ...

  d = 360° -arccos(-3/4) ≈ 221.41°

Then cos(c+d) = cos(327.67°) ≈ 0.84498

This is a positive irrational number, greater than 21/100, so the only reasonable choice is the last one:

  \dfrac{21+24\sqrt{7}}{100}\approx 0.84498

_____

Perhaps you want to work this out using the trig identities.

  cos(c) = -√(1 -sin(c)²) = -7/25

  sin(d) = -√(1 -cos(d)²) = -(√7)/4

Then the desired cosine is ...

  cos(c+d) = cos(c)cos(d) -sin(c)sin(d)

  cos(c+d) = (-7/25)(-3/4) -(24/25)(-√7/4)

  cos(c+d) = (21 +24√7)/100 . . . . matches choice D

Mina created a miniature rocket launcher, and the graph shows the height of one of her
Kazeer [188]

Answer:

Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.

Following the flight of their rocket, calculate the altitude their rocket achieved.

Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.

Conclude the activity by writing a post-flight mission report.

Find the measure of Angle R to the nearest tenth. a. 63.8 degrees b. 67.2 degrees c. 70.9 degrees d. 61.5 degrees
Vikki [24]
The complete question in the attached figure

we know that
 tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
 tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°

the answer is 
R=70.9°
