Answer:
the base of the tree from a stake anchoring the wire is 18.7 ft long
Step-by-step explanation:
A guy wire for a tree is 20 ft. long, making a 21 degree angle with the ground.
It forms a right angle triangle. the hypotenuse of the triangle is 20 ft
The adjacent side of the given angle 21 degree is the base of the tree from a stake
Let x be the base length
the base of the tree from a stake anchoring the wire is 18.7 ft long
Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches
if this helped brainliest would be epic
23-34=12 is because I need the answer to be correct that I’m not mad
Hello there ^ _ ^
121x² + 64 = 0
121x² = 0 - 64
121x² = -64
x² = 64/121
Now take square root
x = +/-√-64/121
I hope this help!
Answer:
x = -8 please mark brainliest
Step-by-step explanation:
Pull out like factors :
-x - 8 = -1 • (x + 8)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-8 = 0
Add 8 to both sides of the equation :
-x = 8
Multiply both sides of the equation by (-1) : x = -8
