Ten and five hundredths in decimal form is 10.05
Answer:
Step-by-step explanation:
<em>See attached diagram (not to scale). </em>
<em>All given details reflected.</em>
a) <u>Find the measure of XZ using the law of cosines:</u>
- y = √(5² + 3² - 2*5*3*cos 135°) = 7 km (rounded)
b) <u>Now using the law of sines find the measure of angle X:</u>
- 7 / sin 135° = 5 / sin X
- sin X = 5 sin 135° / 7
- m∠X = arcsin (5 sin 135° / 7 ) = 28° (rounded)
<u>The bearing of Z from X is:</u>
$6.00 X 8% $6.48
this is the answer. hope this helps
I got -10
1. create two ordered pairs based on the data so (1, 90) and (3, 70)
2. plug into the slope formula so (70 - 90)/(3 - 1)
then it's -20/2, which is -10
Given we don't know which is the hypotenuse, either FE is, or DF is. Note it can't be DE as the hypotenuse is the longest side and you already know FE is longer than DE.
<span>According to pythagoras: </span>
<span>either FE² = DE² + DF² </span>
<span>or DF² = DE² + FE² </span>
<span>8² = 6² + x² </span>
<span>x² = 64 - 36 </span>
<span>x = √28 = 5.291... </span>
<span>Not one of the given answers so... </span>
<span>x² = 6² + 8² </span>
<span>x² = 36 + 64 </span>
<span>x = √100 = 10 </span>
<span>answer: B) 10 for the frist one</span>
