1 answer:

5 0

The answer is 14.5 degrees because and acute triangle is less than 90 degrees and you subtract 75.5 from 90 and you get 14.5. Hope I helped you

AB=11-4=7

$\\ \rm\hookrightarrow \dfrac{BC}{AB}=\dfrac{CE}{ET}$

ET be x

$\\ \rm\hookrightarrow \dfrac{4}{7}=\dfrac{8}{x}$

$\\ \rm\hookrightarrow 4x=56$

$\\ \rm\hookrightarrow ET=x=14$

Triangle J K L is shown. Angle K L J is a right angle. The length of hypotenuse K J is 10.9 centimeters and the length of L J is

scZoUnD [109]

Answer:

sin−1(StartFraction 8.9 Over 10.9 EndFraction) = x

Step-by-step explanation:

From the given triangle JKL;

Hypotenuse KJ = 10.9

Length LJ is the opposite = 8.9cm

The angle LKJ is the angle opposite to side KJ = x

Using the SOH CAH TOA Identity;

sin theta = opp/hyp

sin LKJ = LJ/KJ

Sinx = 8.9/10.9

x = arcsin(8.9/10.9)

sin−1(StartFraction 8.9 Over 10.9 EndFraction) = x
