Answer:
33.55°
Step-by-step explanation:
let alpha be X
sin x= √11/6
sin x= 0.5527
x= sin-1 0.5527
x= 33.55°
Answer: X = 7√2
Step-by-step explanation:
Let first Consider triangle BDC,
Cos C = adjacent/ hypothenus
Cos C = 7 / x ...... (1)
Also, let consider triangle ABC
Cos C = adjacent / hypothenus
Cos C = x / 14 ....... (2)
Since angle C is the same, equate equation 1 to 2
7/ x = x / 14
Cross multiply
X^2 = 98
Make x the subject of formula
X = sqrt (98)
X = sqrt ( 49 × 2 )
X = sqrt (49) × sqrt (2)
X = 7 sqrt(2)
X = 7√2

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
n = 5m
n = 2/3m - 13
<u>Step 2: Solve for </u><em><u>m</u></em>
<em>Substitution</em>
- Substitute in <em>n</em>: 5m = 2/3m - 13
- Subtract 2/3m on both sides: 13/3m = -13
- Divide 11/3 on both sides: m = -3
<u>Step 3: Solve for </u><em><u>n</u></em>
- Define equation: n = 5m
- Substitute in <em>m</em>: n = 5(-3)
- Multiply: n = -15
