Answer:
4.1 cm
Step-by-step explanation:
The segment marked x bisects the chord, so the triangle shown has legs x and 7.8, and hypotenuse 8.8.
The Pythagorean theorem can be used to find x:
8.8² = x² +7.8²
x² = 8.8² -7.8² = 77.44 -60.84 = 16.60
x = √16.6
x ≈ 4.1 . . . cm
Answer:
yes, but there is a better way
Step-by-step explanation:
instead of multiplying x+3 on both sides, I would instead subtract 2 on both sides. If you do this, it would be easier to write this equation in standard form and find the intervals.
Answer:
120 degrees.
Step-by-step explanation:
The 5 exterior angles sum to 360 degrees.
So the 5th exterior angle = 360 - 4(60)
= 360 - 240
= 120 degrees.
