HELP How would I find C? would I have to subtract 180 from 50??

Mathematics

Ahat [919]3 years ago
4 0

Answer:

m∠C = 115°

Step-by-step explanation:

DE≈DF

ΔDEF is an isosceles triangle ∴ m∠DEF = m∠DFE = 1/2 (180-50) = 65

∴ m∠DFB = 180 -65 = 115

∵ DCBF is a parallelogram m∠DFB = m∠DCB = 115°

Let d1 be the diameter of the moon and d2 and be the diameter of the earth.Let r1 be the radius of the moon and r2 be the radius of the earth.

given \: d1 =  \frac{1}{4}d2 \\ = > 2r1 =  \frac{1}{4} ×2r2  \\  =>r1 =  \frac{1}{4}×r2 \\ Now,  \: ratio \:  of \:  \:  their  \: surface \:  areas \:  is:  \\ =  s1: s2 \\  = r {1}^{2}: r {2}^{2} \\ = {1}^{2 } : {4}^{2 } \\ =1:16

Identify which lines are parallel y=(1/2)×+4
castortr0y [4]
Parallel lines share the same slope.  Thus, every line in the form y=(1/2)x+n will be parallel, where n is some constant.

Please help me i need to finish this i’m tired (please use grid if you can) asap!!!

The linear equation is y = 4x - 4

And the graph of the linear equation can be seen in the image below.

<h3>How to graph the last line?</h3>

It seems that you already are good at graphing, so I will try to explain how to find the equation more in detail.

Remember that a general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this case, we know that the y-intercept is -4, then b = -4, replacing that we get:

y = a*x - 4

Now we also can see that this line passes through the point (2, 4), this means that if we evaluate in x = 2, the outcome should be y = 4, replacing that we get:

4 = a*2  - 4

4 + 4 = a*2

8 = a*2

8/2 = a = 4

Then the slope is 4, and the linear equation is:

y = 4x - 4

The graph is below.

The cost of a lack has increased by 30% to £65. Work out the original price
Sveta_85 [38]
Cost of lack increased by 30%

new cost of lack will be = 100% + 30% = 130%

We are given that new cost = £65

Thus 130% of original cost = 65

100% of original cost = 65 × 100/130 = £50

Thus original price was £50
