Find the measure of the missing angle *

Mathematics
1 answer:
sergeinik [125]3 years ago
8 0

Answer:

≈ 49.9° and ≈ 71.0°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin? = \frac{opposite}{hypotenuse} = \frac{13}{17} , then

? = sin^{-1} (\frac{13}{17} ) ≈ 49.9° ( to the nearest tenth )

----------------------------------------------------------------

Using the cosine ratio in the right triangle

cos? = \frac{adjacent}{hypotenuse} = \frac{14}{43} , then

? = cos^{-1} (\frac{14}{43} ) ≈ 71.0° ( to the nearest tenth )

Algebra:please answer #1 and show work
Novay_Z [31]
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
