Find the value of x (really need help with this)

Mathematics
1 answer:
qwelly [4]3 years ago
4 0

Answer:

x=-7

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

40 + x+57 + 90 =180

Combine like terms

187 +x = 180

Subtract 187 from each side

187-187 +x = 180-187

x = -7

The figure is a circle with center O.
STatiana [176]

<u>Given</u>:

Given that the circle with center O.

The radius of the circle is OB.

The chord of the circle O is PQ and the length of PQ is 12 cm.

We need to determine the length of the segment PA.

<u>Length of the segment PA:</u>

We know that, "if a radius is perpendicular to the chord, then it bisects the chord and its arc".

Thus, we have;

PA=\frac{PQ}{2}

Substituting the value PQ = 12, we get;

PA=\frac{12}{2}

PA=6 \ cm

Thus, the length of the segment PA is 6 cm.

Hence, Option d is the correct answer.

X 2x+24<br> Please help me I don’t know what to do
valkas [14]

Answer:

x = 52°

Also, you can use this formula for any other angles. For example, input 90° instead of 180°. I have a feeling that you didn't understand this before. Maybe this will help.

Step-by-step explanation:

180° = x+2x+24°

180° = 3x° + 24°

180° - 24° = 3x

156° = 3x

x = 52°
