Answer:
10:8 or 10 to 8
both the same thing worded differently.
Step-by-step explanation:
There are 10 erasers and 8 pencils so you say 10:8
The height of the triangle is 8root3 meters.
We have given that,
A tree breaks due to a storm and the broken part bends,
So that the top of the tree touches the ground making an angle of 60 degrees with the ground.
The distance between the feet of the tree to the point where the top touches the ground is 16m.
Let the Height of the Tree =AB+AD
and given that BD=8 m
Now, when it breaks a part of it will remain perpendicular to the ground (AB) and the remaining part (AD) will make an angle of 30 degrees.
Now, in △ABD
cos(30)=BD/AD=BD=root3AD/2
AD=2(8)/root3
also in the same triangle
<h3>What is the height of the triangle?</h3>
Height of the tree=AB+AD
Therefore the height of the triangle is 8root3.

I think its 15+y or 15y im not surw
<u>Answer</u>:
x = 155°
<u>Step-by-step explanation</u>:
most left upper angle = 180° - 35° - 90° = 55°
inner middle top angle = 180° - 60° - 55° = 65°
inner middle has right angle, that is 90°
inner middle bottom angle is then, 180 - 90° - 65° = 25°
then as x lies on a straight line with 25°
x + 25° = 180°
x = 180° - 25°
x = 155°
