<h2>These measurements will not form a triangle.</h2>
Step-by-step explanation:
We have sine formula
Given
a = 9.7
b = 49
A = 26°
Substituting
Value of sin B is greater than 1, which is not possible.
Hence these measurements will not form a triangle.

Answer:
x = 58
Step-by-step explanation:
The external angle is half the difference of the intercepted arcs.
(160° -x°)/2 = 51°
160 -102 = x = 58
Answer: 10.8 x 2.22
Step-by-step explanation: You do this because 2.22is equal to one pound, so to figure out 10.8 pounds you multiply
Equation of the parabola: y = ax^2 + bx + c. Find a, b, and c.
x of axis of symmetry:
x

a
=

-> b = -6a
Writing that the graph passing at point (1, 0) and point (4, -3):
(1) 0 = a + b + c -> c = - a - b = - a + 6a = 5a
(2) -3 = 16a + 4b + c --> -3 = 16a - 24a + 5a = -3a --> a = 1
b = -6a = -6; and c = 5a = 5

Check with x = 1: -> y = 1 - 6 + 5 = 0. OK
