sure
Step-by-step explanation:
Answer:
I think the triangle is not a parallelogram because it is three sided. A parallelogram needs 4 sides.
Step-by-step explanation:
Let the x ml of water be mixed with 237 ml of ammonia whose strength is 100%, in order to create a mixture of 75% strength.
The equation required to solve this will be:
237/(237+x)=75/100
solving for x we get:
237/(237+x)=3/4
237×4=3(237+x)
948=711+3x
3x+711=948
3x=948-711
3x=237
x=237/3
x=79 ml
therefore the amount of water to be added will be 79 ml
Answer: anyway i hope this will help
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. Corresponding sides of similar polygons are in proportion, and corresponding angles of similar polygons have the same measure.
Step-by-step explanation:
Formal notation. The wavy line symbol means 'similar to'.
Rotation and reflection. Polygons can still be similar even if one of them is rotated, and/or mirror image of the other. In the figure below, all three polygons are similar.
The numerical length of ST is 16
<h3>How to determine the numerical length of ST?</h3>
The given parameters are:
ST = 2x + 6
TU = 4
SU = 4x
The above parameters can be represented as:
SU = ST + TU
This gives
4x = 2x + 6 + 4
Evaluate the like terms
2x = 10
Divide by 2
x= 5
Substitute x= 5 in ST = 2x + 6
ST = 2 * 5 + 6
Evaluate
ST = 16
Hence, the numerical length of ST is 16
