Answer:

12/13

Step-by-step explanation:

The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.

Then:

cos(θ) = 24/26 = 12/13

Answer:

Therefore,

$BC=y=10.61\ units\\\\AC=x=8.6\ units$

Step-by-step explanation:

Consider a Δ ABC with

m∠ B= 45°

m∠ C = 90°

AB = c = 15 cm

To Find:

BC = a = y ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\\angle B +35+90+=180\\\therefore m\angle A =180-125=55\°$

We know in a Triangle Sine Rule Says that,

In Δ ABC,

$\frac{a}{\sin A}= \frac{b}{\sin B}= \frac{c}{\sin C}$

substituting the given values we get

$\frac{a}{\sin 55}= \frac{b}{\sin 35}= \frac{15}{\sin 90}$

∴ $\frac{y}{\sin 55}= \frac{15}{1}\\\\y=\sin 55\times 15\\\\y=10.606\\\therefore BC = y = 10.61\ units$

Similarly for 'x',

$\frac{x}{\sin 35}= \frac{15}{1}$

$\therefore x =\sin 35\times 15\\\therefore x =0.5735\times 15\\\therefore x =8.6\\$

Therefore,

$BC=y=10.61\ units\\\\AC=x=8.6\ units$

How to graph y=-4|x+2|-5

Elina [12.6K]

$y= -4|x+2| -5 \\ \\x= -6 \Rightarrow y=-4|-6+2|- 5= -4|-4|- 5= -4*4 -5 =\\ \\=-16-5=-21\\ \\ \\x= -4\Rightarrow y=-4|-4+2|- 5= -4|-2|- 5= -4*2 -5 =\\ \\ =-8-5=-13\\ \\ \\x= -2 \Rightarrow y=-4|-2+2|- 5= -4|0|- 5= -4*0 -5 =-5\\ \\ \\x= 0 \Rightarrow y=-4|0+2|- 5= -4|2|- 5= -4*2 -5 =-8-5=-13\\ \\ \\x= 2 \Rightarrow y=-4|2+2|- 5= -4| 4|- 5= -4*4 -5 =-16-5=-21$
