Answer:

y = 10 PLEASE GIVE BRAINLIEST

Step-by-step explanation:

The angles of this triangle should all add up to 180 degrees.

There are 3 angles so 180 ÷ 3 = 60. Each angle will = 60 degrees.

To find y:

5y + 10 = 60

5y = 60 - 10

5y = 50

y = 50 ÷ 5

y = 10

What is the value of log(x exponent 2 y exponent 3 divided by z) when given the following:

Gekata [30.6K]

Answer:

B. 13

Explanation:

$\sf\:Given\:expression: log(\dfrac{x^2 y^3}{z} )$

Logarithm rules:

$\sf (i) \ \sf log(ab) = log(a) + log(b)\\ \\ (ii) \ log(a/b) = log(a) - log(b)\\\\ (iii) \ log(a^n) = n log(a)$

Breakdown of the expression:

$\rightarrow \sf log\left(\dfrac{x^2y^3}{z}\right)$

$\rightarrow \sf log\left(x^2\right) + log\left(y^3\right) - log(z)$

$\rightarrow \sf 2\log\left(x\right)+3\log \left(y\right)-\log \left(z\right)$

insert given values

$\rightarrow \sf 2(3)+3(2)-(-1)$

$\rightarrow \sf 13$

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!! QUESTION ATTACHED

DIA [1.3K]

Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
 10x- 9 = 9x

Subtract 9x from each side: x - 9 = 0

Add 9 to each side: x = 9

Now that we know what 'x' is, we can find the size of Angles-5 and -7 .

Angle-7 = 9x = 81° .

Now look at Angle-6 ... the one that's the answer to the problem.

Angle-6 and -7 together make a straight line, so they must
add up to 180°.

 Angle-6 + 81° = 180°

Subtract 81° from each side: Angle-6 = 99° .
