Answer:
Step-by-step explanation:
okay so you can take any two points 1 x one y in the form (x, y) and (x, y) so
(2, 5) and (4, 1)
then use the slope formula y2-y1/ x2 -x1
1-5+=4
4-2=2
slope equals 4/2 simplified equals 2
I THINKKKKK!
Answer:
AB =24
Step-by-step explanation:
So, since all the sides are equal, you can just take two of the sides and set em equal to each other to find x and then, solve for AB
4x+8 =6x
8= 6x-4x
8=2x
8/2 =x
x= 4
Now, find AB, which is 4x+8
4(4) + 8
16+8 = 24
Hope this helps!

Answer:
70°
Step-by-step explanation:
Connect the center of the circle with endpoints of the chord. Let the center of the circle be point O and endpoints of the chord be points A (let point A lie on the tangent line too)and B.
From the figure, central angle AOB has the measure of 220°.
Consider triangle AOB. This triangle is isosceles triangle because OA and OB are both radii. In this triangle the measure of angle AOB is 360° - 220° = 140°.
Angles OAB and OBA are angles adjacent to the base AB, so they are congruent. The sum of the measures of all interior angles in triangle is always 180°, so
m∠OAB + m∠OBA + m∠AOB = 180°
m∠OAB = m∠OBA = 1/2 (180° - 140°)
m∠OAB = 20°
Since drawn line is tangent line, then OA is perpendicular to this tangent line and
x° = 90° - 20°
x° = 70°

Answer is 74. Greater than 70 less than 80 so some where in the 70s. It has 4 ones so it would be 74.
