Answer:

Step-by-step explanation:

180°-104°=76°( sum of angles A and B)

76°÷2=38°

x=38°

Bcuz it is an isosceles triangle ( a triangle with 2 equal sides). So, angle B and A are equal. thats why 76° must be divided by 2.

180°-104°=76°(angles on a straight line)

180°-76°=104° (sum of angle A and C)

104°÷2=52°

y=52°

it is also an isosceles triangle.

x+y=38+52=90°

Do a proportion
60/100= x/54

Cross multiply and divide
54 x 60= 3,240
3,240 divided by 100 is 32.4

Now subtract
54- 32.4= 21.6
Answer is $21.6

Solve the given equation by completing the square.

Dmitriy789 [7]

Answer:

a = -4, b = 3 and c = 6 (OR)

a = -4, b = -3 and c = 6

Step-by-step explanation:

$x^{2} +8x = 38$

Add 16 to both sides.

$x^{2} +8x+16 = 38 + 16$

$(x+4)^{2} =54$

$x + 4 = \sqrt{54}$ or $x + 4 = -\sqrt{54}$

$x+4=3\sqrt{6}$ or $x+4=-3\sqrt{6}$

$x=-4+3\sqrt{6}$ or $x=-4-3\sqrt{6}$

Therefore, a = -4, b = 3 and c = 6 (OR)

a = -4, b = -3 and c = 6
