1 answer:
UkoKoshka [18]3 years ago

Answer:

x = 20°

y = 70°

Step-by-step explanation:

the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)

in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°

to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°

Virty [35]

Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.

Increase= (277-210)/210

67/210

Then it ends up as 0.319047619...

Multiply that by 100 to make it a percent, which is..

31.9047619..

Solve square root <br> X^2+12x+43=0
AlekseyPX
x^2+12x+43=0&#10; 

x= \dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a} 

x= \dfrac{-12+ \sqrt{12^2-4*43} }{2},\dfrac{-12- \sqrt{12^2-4*43} }{2} 

x= \dfrac{-12+2 \sqrt{7i} }{2}, \dfrac{-12-2 \sqrt{7i} }{2} 

x=-6+ \sqrt{7i},-6- \sqrt{7i}
