Answer: 108
Step-by-step explanation: You take the x and the 2/3x and combine them to get 1 2/3x, so 1 2/3x=180. 180 divided by 5 is 36, and 36 times three is 108
Answer:
15.7
Step-by-step explanation:
The equation for finding the circumference of a circle is
2 x pi x r(radius). Radius is half the diameter.
5/2=2.5
2 x 3.14 x 2.5
=15.7
Answer:
Given triangle ABC with altitude segment BD labeled x. Angles ADB and CDB are right angles by _____1._____, making triangle ABD and triangle BCD right triangles. Using the trigonometric ratios sine of A equals x over c and sine of C equals x over a. Multiplying to isolate x in both equations gives x = _____2._____ and x = a ⋅ sinC. We also know that x = x by the reflexive property. By the substitution property, _____3._____. Dividing each side of the equation by ac gives: sine of A over a equals sine of C over c.
Step-by-step explanation:
Answer:4.25, so about 4 or 5
Step-by-step explanation:
1/4 = x/17
-Cross multiply-
4*x = 1*17
4x = 17
-divide-
17/4 = x
x = 4.25
