Answer:
18.0
Step-by-step explanation:
==>Given:
Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°
==>Required:
Value of x to the nearest tenth
==>Solution:
Using the Cosine rule: c² = a² + b² - 2abcos(C)
Let c = x,
a = 16
b = 30
C = 30°
Thus,
c² = 16² + 30² - 2*16*30*cos 30°
c² = 256 + 900 - 960 * 0.8660
c² = 1,156 - 831.36
c² = 324.64
c = √324.64
c = 18.017769
x ≈ 18.0 (rounded to nearest tenth)
Answer:
13,841,287,201
Step-by-step explanation:
simply the parenthesis:
7^6 or 7 times itself 6 times: 7x7x7x7x7x7
which equals 117,649 and then multiply that number by itself
117,649x117,649 and you should get 13,841,287,201
Answer: x=10 7/8
Step-by-step explanation:
Subtract 3/4 from both sides. Multiply both sides by 3. Divide both sides by 2 (basically just isolate x on one side of the equal sign).
Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then x = 6 cm
Perimeter = 4x = 4(6) = 24 cm
