What is the measure of angle A

Mathematics
1 answer:
Arisa [49]3 years ago
8 0

Answer:

27.7°

Step-by-step explanation:

To find m<A, apply trigonometric function.

Reference angle = A

Side length opposite to A = 20

Hypotenuse = 43

Apply SOH, which is:

Sin (A) = \frac{Opp}{Hyp}

Plug in the values

Sin (A) = \frac{20}{43}

A = sin^{-1}(\frac{20}{43})

A ≈ 27.7° (nearest tenth)

What is "the sum of twice a number and six is the same as three subtracted from the number itself"?
inysia [295]

Answer:

x=-1

Step-by-step explanation:

2x+6=3-x

Step 1: Simplify both sides of the equation.

2x+6=3−x

2x+6=3+(−x)

2x+6=−x+3

Step 2: Add x to both sides.

2x+6+x=−x+3+x

3x+6=3

Step 3: Subtract 6 from both sides.

3x+6−6=3−6

3x=−3

Step 4: Divide both sides by 3.

3x/3=−3/3

x=−1

Answer:

x=−1

onsider the equation 0.5 times e4z =13 solve the equation for z. express the solution as a logarithm in base e
olga_2 [115]

Answer:

z=\frac{ln(26)}{4}

Step-by-step explanation:

The given equation is:

0.5\,e^{4z}=13

so, we first isolate the exponential form that contains the unknown "z" in the exponent, by dividing both sides by 0.5:

0.5\,e^{4z}=13\\e^{4z}=\frac{13}{0.5}\\e^{4z}=26

Now we bring the exponent down by applying the natural log function on both sides, and then solve for "z":

e^{4z}=26\\ln(e^{4z})=ln(26)\\4\,z=ln(26)\\z=\frac{ln(26)}{4}

What is a 5% increase from $79?
amid [387]
We can use the rule of three to figure out what's 5% of 79:

100/79=5/x

x= (79*5/100)=3.95
Let's add said 5% to 79:
79+3.95=82.95
