2 #'s whose sum is 51: x + y = 51
2 #'s whose difference is 13: x - y = 13

add the 2 equations: 2x = 64 ⇒ x = 32
using either equation find y: 32 + y = 51 ⇒ y = 19
Answer the 2 #'s are 32 and 19

Given f(x)=x^2-3andg(x)=x+1. The composite function g•f is

Bezzdna [24]

$f(x) = {x}^{2} - 3 \\ g(x) = x + 1 \\ gf(x) = you \: put \: f(x) \: into \: g(x). \\ \\ gf(x) = {x}^{2} - 3 + 1 \\ gf(x) = {x}^{2} - 2 \\$

Find the measure of each acute angle in the figure.

Artist 52 [7]

Answer:

Angle 1 = 46°

Angle 2 = 44°

Step-by-step explanation:

Given:

Angle 1 = (4x - 2)°

Angle 2 = (3x + 8)°

Angle 3 = 90°

Find:

All acute angle

Computation:

Using angle sum property

Angle 1 + Angle 1 + Angle 1 = 180°

(4x - 2)° + (3x + 8)° + 90° = 180°

7x + 6 = 90

7x = 84

x = 12°

So,

Angle 1 = (4x - 2)° = 4(12) - 2 = 46°

Angle 2 = (3x + 8)° = 3(12) + 8 = 44°
