By Pythagorean Theorem, a^2 + b^2 = c^2
so 8^2 +15^2 = c^2
64+225 = 289
sqr rt of 289 is 17
The answer is B. I used the trigonometric sine formula
And
Answer:31.4cm
Step-by-step explanation:
Circumference=2×π×(diameter/2)
Circumference=2×3.14×10/2
Circumference=(2×3.14×5)
Circumference=31.
Answer:
Step-by-step explanation:
a)3*4*2*b = 24b
Multiply the numerals and then the variables.When multiply variables, add the exponents and only same variables can be multiplied
b) c⁵ *c = c⁵⁺¹ = c⁶
c) 2y⁴ *5y³ = 2*5 * y⁴⁺³ = 10y⁷
Answer:
|GH| = 5,7 cm
Step-by-step explanation:
To know |GH|, you first need to find the length of |GD|.
We can calculate |GD| by;
cosG = |GC| / |GD|
<=> |GD| = |GC| / cosG
=> |GD| = 3,9 cm/ 0,62 = 6,33 cm
We now can easily calculate |GH| with the sinus of angle D;
sinD = |GH| / |GD|
<=> |GH| = sinD.|GD|
=> |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm
I hope i did not make a mistake ...
