Find the measure of Angle A. (include and explanation so I could do the rest on my own, preferably :)
castortr0y [4]

Answer:

13) Angle A is 30°

14) Angle A is 45°

15) Angle A is 40°

16) Angle A is 40.5°

Step-by-step explanation:

By the angle sum theorem for the interior angles of a triangle, we have;

13) 130° + 2·x + 3·x = 180°

∴ 2·x + 3·x = 180° - 130° = 50°

2·x + 3·x = 5·x = 50°

x = 50°/5 = 10°

∠A = 3·x = 3 × 10° = 30°

∠A = 30°

14) 3·x + 9 + 4·x + 9 + 78° = 180°

7·x + 18 + 78° = 180°

7·x = 180° - (18 + 78)° = 180° - 96° = 84°

x = 84°/7 = 12°

∠A = 3·x + 9 = 3 × 12° + 9 = 45°

∠A = 45°

15) 90° + x + 51 + x + 61 = 180°

∴ x + 51 + x + 61 = 180° - 90° = 90°

2·x + 112 = 90°

2·x = (90 - 112)° = -22°

x = -22°/2 = -11°

x = -11°

∠A = x + 51 = -11° + 51 = 40°

∠A = 40°

16) x + 79 + x + 49 + 70° = 180°

x + x  = (180 - 70 - 79 - 48)° = -17°

2·x = -17°

x = -17°/2 = -8.5°

x = -8.5°

∠A = x + 49 = (-8.5 + 49)° = 40.5°

∠A = 40.5°.

Absolute value inequalities. 10-4|9y-10|<-94
Ivahew [28]

Answer: \begin{bmatrix}\mathrm{Solution:}\:&\:y4\:\\ \:\mathrm{Decimal:}&\:y4\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-\frac{16}{9}\right)\cup \left(4,\:\infty \:\right)\end{bmatrix}

Step-by-step explanation:

10-4\left|9y-10\right|

10-4\left|9y-10\right|-10

-4\left|9y-10\right|

\left(-4\left|9y-10\right|\right)\left(-1\right)>\left(-104\right)\left(-1\right)

4\left|9y-10\right|>104

\frac{4\left|9y-10\right|}{4}>\frac{104}{4}

\left|9y-10\right|>26

9y-1026

Uh I'm confused on how to do this may someone help?
vlada-n [284]

Answer:

5

Step-by-step explanation:

Use the distance formula

\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}

\sqrt{(-2+7)^{2}+(4-4)^{2}}

\sqrt{5^{2}}=5

You can also just subtract: -2-(-7) to get 5 because the y-values are the same
