Answer:

x = 13

39° and 51°

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

This is a right angle triangle, so one side has a size of 90 degrees.

3x + 4x - 1 + 90 = 180

7x + 89 = 180

7x = 91

x = 91/7

x = 13

Put x as 13 to work out the size of the angles.

3(13) = 39

4(13) - 1

52 - 1 = 51

Answer:

x = 13 \\

Measure of the angles

39 \:  \: degrees \\ 51 \:  \: degrees

Step-by-step explanation:

<em>sum</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>interior</em><em> </em><em>angles</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>triangle</em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em>

<em>3x + 4x - 1 + 90 =1 80 \\ 7x + 89 =1 80 \\ 7x = 180 - 89 \\ 7x =9 1 \\  \frac{7x}{7}  =  \frac{91}{7}  \\ x = 13</em>

<em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em><em>,</em>

<em> </em><em>now</em><em> </em><em>lets</em><em> </em><em>work</em><em> </em><em>out</em><em> </em><em>for</em><em> </em><em>the</em><em> </em><em>angles</em>

<em>3x \\ 3 \times 13 \\  = 39</em>

<em>4x - 1 \\ 4 \times 13 - 1 \\ 52 - 1 \\  = 51</em>

The triangle below is isosceles. Find the length of side xx in simplest radical form with a rational denominator.
coldgirl [10]

Answer:

Solution given:

Since the given triangle is isosceles and right angled triangle

perpendicular [p]=base[b]=x

hypotenuse [h]=6

we have

by using Pythagoras law

p²+b²=h²

x²+x²=6²

2x²=36

x²=36/2

x²=18

x=\sqrt{18}

<u>x</u>=\bold{3\sqrt{2}}

Derrick's parents are finalizing a budget for his college expenses. His first year of college will cost $8,000, and his
pychu [463]
The first answer



Step by step

His first year costs $8,000
So our total amount to start with is $8,000

His second year will cost 12% more than his first so $8,000 • 1.12 = $8,960
Our total is now $16,960

His third year will again will be 12% more than his last year so $8,960 • 1.12 = 10,035.2
Our total is now $26,995.2

His last year will be 12% more than his previous year so $10,035.2 • 1.12 = $11,239.42
Our final total is $38,234.62
Which rounded equals $38,235
