Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

17x + 10x -5 + 50 = 180

Combine like terms

27x + 45 = 180

To find the valu of x, we have to isolate x. To isloate x

Step 1: Subtract 45 from both sides

27x = 180 - 45

27x = 135

Step 2: Divide both sides by 27

x = 135/27

x = 5

Solve for x^2 +11 + 121/4 = 125/4 for x

Ratling [72]

I hope this helps you

x^2 =125/4-121/4-11

x^2=4/4-11

x^2=1-11

x^2= -10

x= i.square root of 10

What is the measure of angle J in the triangle below? A. 99 B. 42 C. 9 D. 48

Leya [2.2K]

For this use the law of sines:
$\sin( \alpha ) \div a = \sin( \beta ) \div b \\ \sin( \alpha ) \div 11 = \sin(103) \div 16$
$\frac{ \sin( \alpha ) }{11} = \frac{0.97}{16}$
cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
hit the "arcsin" button on your calculator:
${ \sin}^{ - 1} (0.67) = 42.06 = 42.1 \: deg$
therefore answer B. 42 is the correct answer!!
