Angles T and V are country that angle T has a measure of (2X +10) angle B has a measure of 48° what is the value of X

enyata [817]

If T and V are complementary angles, their sum is 90°.

V + T = 90°
48° + (2X+10)° = 90° . . . . . . . substitute given information
2X + 58 = 90 . . . . . . . . . . . . .. collect terms
2X = 32 . . . . . . . . . . . . . . . . .. subtract 58
X = 16 . . . . . . . . . . . . . . . . . .. divide by 2

The value of X is 16.

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

<em /> $\displaystyle V_P = 2x^3 - 6x^2 + 8x$ <em />

<em /> $\displaystyle V_C = 27x^3$ <em />

<em />

<u>Step 2: Find Combined Volume</u>

[Set up] Add: $\displaystyle V_P + V_C = V_{P + C}$
Substitute in variables: $\displaystyle V_{P + C} = 27x^3 + 2x^3 - 6x^2 + 8x$
Combine like terms: $\displaystyle V_{P + C} = 29x^3 - 6x^2 + 8x$
