Answer:
∠ GDH = 67.5°
Step-by-step explanation:
The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ GDH =
(GH + EF) =
(90 + 45)° = 0.5 × 135° = 67.5°
The terms are -80, 4p, and -6z.
The coefficients are 4 and 6.
Terms are separated by the addition and subtraction sign.
Coefficients are the numbers that go in front of the variable.
<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is
. We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression
to be the side of the square.
As the function forms the square after adding some
unit tiles, 

From comparision, 
∴ 8 more unit tiles are required to complete the square.
(3.2 • 10^8)(1.3 • 10^9)
= 4.16 • 10^17 in scientific notation
