Find the measure of angle x in the figure below: A triangle is shown. At the top vertex of the triangle is a horizontal line ali

VLD [36.1K]

Answer:

$x=35^\circ$

Step-by-step explanation:

From the diagram which I have drawn and attached below:

$56^\circ+y+51^\circ=180^\circ$ (Sum of Angles on a Straight Line)\\y=180^\circ-(56^\circ+51^\circ)\\y=73^\circ$

Next, in the triangle, the sum of the three interior angles:

$y+x+72^\circ=180^\circ\\$Since y=73^\circ\\73^\circ+x+72^\circ=180^\circ\\x=180^\circ-(73^\circ+72^\circ)\\x=35^\circ$

The value of angle x is 35 degrees.

Calculate 4 raise to power 2 multiply by 5 raise to poer 2 minus 18 raise to power 2

Paladinen [302]

Answer:

Step-by-step explanation:

4^2 x 5^2 - 18^2

PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.

Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.

(4x4) x (5x5) - (18x 18)

=16 x 25 - 324

Now we multiply: (PEMDAS)

= 400 - 324

then subtract: (PEMDAS)

=76
