Answer:

a = 65°

(what's missing for a half turn)

c = 30°

(bc same angle as upper left)

b = 85°

(bc a+b+c must be 180° in sum, as always in triangles)

Answer:

a = 45

b = 105

c = 30 .

Step-by-step explanation:

a + 135 = 180 {Linear pair}

a = 180 - 135

a = 45

d = 30 {Vertically opposite angles}

WA // YZ

c = d { Alternative interior anlges}

c = 30

a + b+ c = 180 {Angle sum property of triangle}

45 + b + 30 = 180

b + 75 = 180

b = 180 -75

b = 105

Answer:

APY = 0.04 or 4%

Step-by-step explanation:

Given the annual percentage rate of 3.5% that is compounded quarterly, and a principal of $6,500:

We can use the following formula to solve for the annual percentage yield (APY):

$APY = (1 + \frac{r}{n})^n - 1$

where <em>r</em> = interest rate = 3.5% or 0.035

<em> n</em> = number of compounding periods per year = 4

We can plug in the values into the equation:

$APY = (1 + \frac{r}{n})^n - 1$

$APY = (1 + \frac{.035}{4})^4 - 1$

$APY = (1 + 0.00875)^4 - 1$

$APY = (1.00875)^4 - 1$

APY = 1.03546 - 1

APY = 0.04 or 4%

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.

charle [14.2K]

The area of a triangle could be determined using the following formula
$\boxed{a= \frac{1}{2} \times b \times h}$

plug in the numbers
$a = \frac{1}{2} \times 21 \times 12$
$a = \frac{1}{2} \times 252$
$a= \frac{252}{2}$
a = 126

The area of the triangle is 126 square meters

Answer:

The answer is D.

Step-by-step explanation:

The first thing I did was substitute the variables in for x and y. This is the numbers in the answer choices: (x,y). I don't know if there is an easier way to do this, but you can replace the two numbers in for the variables since it's multiple choice.

For example,

A: -2+2*4=6 Isn't right

B: 1+2*-1= -1 Nope

C: (0,0) you can already tell it's not right because anything multiplied by 0 is 0.

D: -4+2*1=-2 This is the correct answer.
