X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
The mistake Shawna made was in her answer the 54 repeats so the bar should be over the .54 not the .545
Answer: C, WXZ and WXU are adjacent angles.
Step-by-step explanation:
A is incorrect because TUX and VUS are vertical angles.
B is incorrect because YXZ and TUX have no relationship.
C is correct because WXZ and WXU are supplementary angles, thus adjacent.
D is inccorect because VUX and TUS are vertical angles.
Answer:
1/3
Step-by-step explanation:
let x=0.333...
10x=3.333...
subtract
9x=3
x=3/9=1/3
Answers:
x = 7
The measure of angle D is 14 degrees
-----------------------------------------------
-----------------------------------------------
Angle C and angle D are complementary, which means they add to 90 degrees.
(angle C) + (angle D) = 90
(12x-8) + (3x-7) = 90
12x-8 + 3x-7 = 90
(12x+3x) + (-8-7) = 90
15x-15 = 90
15x-15+15 = 90+15
15x = 105
15x/15 = 105/15
x = 7
So you have the correct x value. Nice work.
Now use this x value to find the measure of angle D
angle D = 3*x - 7
angle D = 3*7 - 7
angle D = 21 - 7
angle D = 14 degrees
