In the rho.bus, m angle 1 =4y-2. Find the value of y.
IRINA_888 [86]

Answer:

y = 23

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other, thus

∠1 = 90° and ∠1 = 4y - 2, so equating gives

4y - 2 = 90 ( add 2 to both sides )

4y = 92 ( divide both sides by 4 )

y = 23

In the following math problem, which operation should you do FIRST? 8 + 3(72 x 4) – 5 ÷ 2 a. 8 + 3 b. 72 c. 7 x 4 d. 5 ÷ 2
Grace [21]

C - 72 x 4

If using PEMDAS, you can already deduce the exponents and parenthesis. With these gone, you're left with multiplication and division and this is decided by which comes first from left to right. Thus, leaving you with the first multiplication problem presented.

Hope this helps!
