Answer:

Angel two measures 60.4.

Step-by-step explanation

Since you are given one number, you would just have to subtract that from 90. (Easiest way to explain) Complementary angels are when the sum of both angels add up to 90°.

Given: ABCD is a parallelogram and AC bisects BD.<br> Prove: AB is congruent to BC.

earnstyle [38]

Let's see

In ∆ABE and ∆CBE

BE=BE(Common side)
AE=EC[Diagonals of a parallelogram bisect each other]
<AEB=<BEC[90°]

So by

SAS congruence the triangles are congruent

AB=BC

Proved

Fact:-

It's already given AC is perpendicular to BD

It means diagonals are perpendicular to each other

According to general property of rhombus this parallelogram is also a rhombus.

So sides are equal hence AB =BC

PLEASE HELP WITH GEOMETRY IM STUCK!?}

Ilya [14]

Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

$cos(37)=\frac{11}{x}$

step 1 multiply each side by x

$cos(37)*x=xcos(37)\\\frac{11}{x} *x=11$

now we have $xcos(37)=11$

step 2 divide each side by cos(37)

$\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\$

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8

Need help with the problem in the photo.

noname [10]

Answer:

B (1,1) & (2,-1)

Step-by-step explanation:

This is the answer because if a line was drawn through these 2 points the slope would be the same as line QR so therefore the two would be parallel.

Hope this helps :)

Which is the equation of a line with a slope of -1/3 and a y-intercept at (0,1)?

Nutka1998 [239]

Answer:

The answer is

$\huge \boxed{y = - \frac{1}{3}x + 1 }$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (0,1) and slope - 1/3

The equation is

$y - 1 = - \frac{1}{3}(x - 0) \\ y - 1 = - \frac{1}{3} x$

We have the final answer as

$y = - \frac{1}{3} x + 1 \\$

Hope this helps you
