Please help with this, this is for my test review!!!

Answers

Answer:

137°

Step-by-step explanation:

All angles in a triangle add up to 180° always.

Now imagine the two smaller shapes as a bigger triangle, CED.  The measure of angle CED is 89°, and CDE is 48°.  Do the math, and angle DCE is 43°.

But notice how the corresponding sides of the two smaller shapes are congruent.  (CX=XE, and DY=YE)  Meaning, the measure of angle C is equal to the measure of angle YXE.

We're almost there.  CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180.  180-43 = 137°.

Find cos(a) in the triangle.

Answers

Answer:

cos(α) = 24/25.

Step-by-step explanation:

First of all, we'll find the answer just using the fact that ABC is a right triangle in C. So, by the definition of cosine:

[tex]\cos(\alpha) = \dfrac{AC}{AB}\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]

Now, we'll solve the question with another approach. By the Law of Cosines in the triangle ABC:

[tex]BC^2 = AB^2+AC^2-2\cdot AB\cdot AC\cos(\alpha)\\\\7^2 = 25^2+24^2-2\cdot 25\cdot 24\cos(\alpha)\\\\49 = 625+576-1200\cos(\alpha)\\\\1200\cos(\alpha)=1152\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]

Given: 3j+k/2=15-4k; Prove j=10-3k


And Given 5x-2y=x+14; Prove y=2x-7

Answers

Answer:

[tex]j=10-3k[/tex]

[tex]y = 2x - 7[/tex]

Step-by-step explanation:

Solving (a):

Given

[tex]\frac{3j + k}{2}=15-4k[/tex]

Required: Prove [tex]j=10-3k[/tex]

[tex]\frac{3j + k}{2}=15-4k[/tex]

Multiply through by 2

[tex]2 * \frac{3j + k}{2}=(15-4k) * 2[/tex]

[tex]3j + k = 30 - 8k[/tex]

Subtract k from both sides

[tex]3j = 30 - 9k[/tex]

Divide through by 3

[tex]j = \frac{30 - 9k}{3}[/tex]

j = 10 - 3k

Solving (b):

Given

[tex]5x - 2y = x+ 14[/tex]

Required

Prove: [tex]y = 2x - 7[/tex]

[tex]5x - 2y = x+ 14[/tex]

Subtract 5x from both sides

[tex]-2y = x - 5x + 14[/tex]

[tex]-2y = -4x + 14[/tex]

Divide through by -2

[tex]\frac{-2y}{-2} = \frac{-4x}{-2} + \frac{14}{-2}[/tex]

[tex]y = 2x - 7[/tex]
