Answer: x=4.7434

Step-by-step explanation:

Use the pythagorean theorem a^{2} +b^{2} =c^{2}

plug in and solve

x^{2} +3x^{2} =(3\sqrt{10}) ^{2}

4x^{2} =90

x^{2} =22.5

x=4.7424

if you need to solve for the sides

3x = 3(4.7434) = 14.2302

Find x<br>and<br>each of the<br>interior angles.​
Kay [80]

Answer:

Part 1) x=27

Part 2) The measure of the interior angles are 64°-67°-49°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In this problem

(3x-17)^o+(x+40)^o+(2x-5)^o=180^o

Solve for x

Combine like terms

(6x+18)^o=180^o

Subtract 18 both sides

6x=180-18

6x=162

Divide by 6 both sides

x=27

step 2

Find the measure of each interior angle

substitute the value of x in each measure

(3(27)-17)=64^o

(27+40)=67^o

(2(27)-5)=49^o

Solve by factorising x² + 11x + 30 = 0<br> dont get think one could someone explain this please.
nalin [4]

Answer:

x={-5,-6}

Step-by-step explanation:

x²+11x+30=0

x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)

x(x+5)+6(x+5)=0

(x+5)(x+6)=0

so

x+5=0

x+6=0

therefore

x=-5

x=-6
