ANSWER
z  =  43 \degree
EXPLANATION


We want to calculate the value of the angle marked z° in the diagram.

Since the given diagram is a right angle triangle, one of the angles is 90°.


The sum of the angles in a triangle is 180°.


This implies that,

z + 90 \degree+ 47 \degree =  180 \degree


We group like terms to obtain,

z  =  180 \degree - 90 \degree -  47 \degree


We simplify to obtain,


z  =  43 \degree

Answer:

z=43^{\circ}

Step-by-step explanation:

We have been given a right triangle. We are asked to find the measure of angle z for our given triangle.

We know that all interior angles of a triangle add up-to 180 degrees. Using angle sum property, we can set an equation as:

z+47^{\circ}+90^{\circ}=180^{\circ}

z+137^{\circ}=180^{\circ}

z+137^{\circ}-137^{\circ}=180^{\circ}-137^{\circ}

z=43^{\circ}

Therefore, the value of z is 43 degrees.

PLS HELP ASAP! WILL MARK BRAINLIEST<br> sin ∠A =<br><br> 3/5<br> 4/5<br> 3/4<br> 5/4
Dafna11 [192]

Answer:

3/5

Step-by-step explanation:

sohcahtoa

since we're finding sine, we need the opposite and hypotenuse.

opposite of <A=3, hyp of <A=5.

opp comes before hyp in "soh", so sin<A=3/5

Can someone help me please ???????
Inessa [10]

Answer:

d=1

Step-by-step explanation:

Factor d^2 - 2d - 8 into (d-4)(d+2)

Move -2/d+2 onto the other side, changing it into 2/d+2.

\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4}+\frac{2}{d+2} = 0

Let the empty side equal zero.

Add 3/d-4 and 2/d+2

\frac{5d-2}{(d+2)(d-4)}

Then add that to -3d.

\frac{2d-2}{(d+2)(d+4)}

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.

2d=2

d=1

I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.

3cis(5pi/4) in polar form
madreJ [45]
Rectangular form:
z = -2.1213203-2.1213203i

Angle notation (phasor):
z = 3 ∠ -135°

Polar form:
z = 3 × (cos (-135°) + i sin (-135°))

Exponential form:
z = 3 × ei (-0.75) = 3 × ei (-3π/4)

Polar coordinates:
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase)

Cartesian coordinates:
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034

Write the fraction 8/9 as a percent round to the nearest hundredth of a percent were necessary?
Flura [38]

Answer:

A

Step-by-step explanation:

To turn a fraction into a percent, you divide the numerator by the denominator.

8 divided by 9 = .8 repeated

To turn it into a percent, you move the decimal to the right 2 spaces.

.8 turns into 88.8 repeated

Then you round to the nearest hundredth

88.8 repeated rounds to 88.89.
