A/-8+15>23 isn't this weird to you guys too

1 answer:

4 0

Let's solve your inequality step-by-step.

a − 8 + 15 > 23

Step 1: Simplify both sides of the inequality.

−1/8a + 15 > 23

Step 2: Subtract 15 from both sides.

−1/8a + 15 − 15 > 23 − 15

−1/8a > 8

Step 3: Multiply both sides by 8/(-1).

(8/−1) * (−1/8a) > (8/−1) * (8)

a < −64

Therefore, the answer is a < -64! I hope this helped! :)

find the value of x of given figure and solve this question step by step plzz help question number D

Alinara [238K]

Answer:

x=15 cm

Step-by-step explanation:

The two triangles in the diagram are:

ABC and BDC

First we have to find the third side (hypotenuse) of BDC so that we can use it to find the value of x.

Hypotenuse is the largest side of a triangle which is usually in front of the right angle.

So in BDC

$Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm$

Applying Pythagoras theorem:

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm$

Solving for triangle ABC

$Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\$

Applying Pythagoras theorem

$AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm$

Hence,

x=15 cm

Use the given information and a calculator to find to the nearest tenth of a degree

Schach [20]

Answer:

111.4 degrees

Step-by-step explanation:

Let's write cos x = -0.3646. Or, look up the symbols chart at the bottom of your page and click on Ф to obtain this character: cos Ф = -0.3646.

If Ф is in Quadrant III, then the adjacent side is negative and the hypotenuse is positive.

-1

Type this into your calculator: cos -0.3646. Result: 1.934 (radians)

This converts to degrees as follows:

1.934 rad 180 degr

--------------- * --------------- = 111.4 degrees. Note that this angle is in QIII.

1 π rad
