The m∠B is two more than three times the measure of ∠C. If ∠B and ∠C are complementary angles, find the measures of both angles.
allsm [11]

Answer:

B = 68°  and  C = 22°

Step-by-step explanation:

Let angle B's measure be B and angle C's measure be C.

Also note that complementary means that they sum to 90.

Now:

<u>The m∠B is two more than three times the measure of ∠C:</u>

we can write:

B = 3C + 2

<u>If ∠B and ∠C are complementary angles:</u>

B + C = 90

Putting 1st equation in 2nd, we get:

B + C = 90

3C + 2 + C = 90

4C = 90 - 2

4C = 88

C = 88/4 = 22

Now B = 3C + 2, so

B = 3(22) + 2 = 68

Hence, B = 68 degrees and C = 22 degrees

De qué manera relacionas lo que escuchas o lees en tu vida​
nika2105 [10]

Answer:

La forma en que relaciono lo que escucho o leo en mi vida es a través de la interpretación de la información, es decir, todo aquello que leo o escucho es procesado, evaluado e interpretado conforme a mi experiencia, vivencias, estudios e ideología, lo que me permite obtener una conclusión de la información que percibo.

Así, no considero todo lo que leo y escucho como hechos comprobados, sino que lo someto a un análisis exhaustivo y completo respecto de su validez y sus implicancias respecto de mi persona.

Ivan and Tanya share £150 in the ration of 4:1
Zarrin [17]

Answer:

Money Ivan gets   extra = 120 - 30 (or 3x) = 90

Step-by-step explanation:

Ivan = 4x

Tanya = 1x

Total = 150

4x + x = 150

5x = 150 ;  x = 150 / 5 = 30

Ivan = 4x = 120

Tanya = 1x = 30

Money Ivan gets   extra = 120 - 30 (or 3x) = 90

8^3*8^-5*8^y=1/8^2, what is the value of y in the product of powers below?
Aleks04 [339]

For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:

a ^ n * a ^ m = a ^ {n + m}

So, we can rewrite the given expression as:

8 ^ {3-5 + y} = \frac {1} {8 ^ 2}\\8 ^ {- 2 + y} = \frac {1} {8 ^ 2}

So, if y = 0:

8 ^ {- 2} = \frac {1} {8 ^ 2}\\\frac {1} {8 ^ 2} = \frac {1} {8 ^ 2}

Equality is met!

Answer:

y = 0
