1) m∠1 = 360°/8 = 45° . . . . . a regular octagon is 8-way rotationally symmetrical, so each sector is 1/8 of a circle.
2) m∠2 = (180° -45°)/2 = 67.5° . . . . . . the angles of a triangle add to 180°. The base angles of an isosceles triangle are equal.
Answer:
x = 3, x = 0
Step-by-step explanation:
To solve these factored equations, just divide each part by zero and solve.
2x(x-3) = 0 → (x-3) = 0, and 2x = 0.
(x-3) = 0 → x - 3 + 3 = 0 + 3 → <u>x = 3.</u>
2x = 0 → 2x/2 = 0/2 → <u>x = 0.</u>

Answer:
ΔPRQ ≅ ΔVWX
Step-by-step explanation:
ASA means the corresponding side lies between the two corresponding angles. That is true for triangles PRQ and VWX.
We chose to name the triangles starting with the angle marked with the single arc, then the angle marked with the double arc. They can be named using any permutation of the letters, provided that the same correspondence is achieved between the two names.
At first, pg means picogram
A microgram is a unit to measure the mass
Then from both relation
Now we can solve the question
Since the average mass per cell is 67.55 pg
Since the number of cells is 10^5
To find the total mass multiply them
We need to change it to microgram, then multiply it by 10^-6
Put a decimal point at the end of the number and move it 6 places to the left to get the answer
