Since PQ is tangent to the circle, angle PQO is 90°.

Since the sum of angles of any triangle must be 180° we can say:

180-90-12=x thus:

x=78°

The smallest angle in a triangle measures 9 degrees less than the middle angle. The largest angle is 26 degrees more than 3 time

Answer:

Step-by-step explanation:

A+B+C = 180°

A ≤ B ≤ C

B = A+9

C = 3A+26

A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°

5A = 145°

A = 29°

B = A+9 = 38°

C = 3A+26 = 113°

Find the error (-8x^2y^2)^2= -64x^4y^4

ExtremeBDS [4]

Answer:

$(-8)^2\neq-64$

Step-by-step explanation:

Using the distributive property to expand, we have

$(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.$

Squaring each term, we have

$(-8x^2y^2)^2=64x^4y^4.$

The mistake was that $8^2=64,$ not $-64.$ Using the fact that $8^2=64,$ the right answer would be

$\boxed{64x^4y^4}$ .

Solve this equation x2+11x-26=0

goldfiish [28.3K]

Factor it out first so:

y=(x+13)(x-2)

Then you know that x= -13 and 2 to make the equation 0

Hope this helps!

Scilla [17]

Answer:

Step-by-step explanation:

s= student ticket

g= general admisson ticket

4s+6g=2876

s+g=525

4s+6g=2876

-4s-4g=-2100

add both equations

2g=776

g=388

s+g=525

s+388=525

s=137
