Answer:

x = 3

Step-by-step explanation:

add all the sides:

(3x - 4) + (15 - x) + (3x + 6) = 32

simplify - collect like terms:

5x + 17 = 32

5x = 15

x = 3

If geometry symbol represented as small triangle with three sides. abc geometry congruent symbol represented as two small horizo
n200080 [17]

The value of x in the congruent triangles abc and dec is 1

<h3>How to determine the value x?</h3>

The question implies that the triangles  abc and dec are congruent triangles.

The congruent sides are:

ab = de

bc = ce = 4

ac = cd = 5

The congruent side ab = de implies that:

4x - 1 = x + 2

Collect like terms

4x - x = 2 + 1

Evaluate the like terms

3x = 3

Divide through by 3

x = 1

Hence, the value of x is 1

Given that sinΘ = 1/2 and that Θ lies in quadrant II, determine the value of cosΘ.
amm1812

With \theta in quadrant II, we expect to have \cos\theta. Then

\cos^2\theta+\sin^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}

\implies\cos\theta=-\dfrac{\sqrt3}2
