Geometry? i am really bad at math and have dyscalcullia. .

We see from the figure,

1. ∠LON and ∠MON both measure = 90°

2. LO = OM = 2 units

3. ΔLON and ΔMON share the side ON

Since, in both triangles, we have LO=OM, ∠LON = ∠MON and ON=ON.

4. ΔLON and ΔMON are congruent by SAS Postulate

5. We have, ΔABC and ΔA'B'C' are congruent.

It can be seen that, they are congruent by applying the transformations,

Reflection across x-axis followed by translation of 3 units upwards.

The answers are (1). 90°, (2) 2 units, (3) ON, (4) Side-angle-side, (5) A.

Step-by-step explanation:  Based on the attached file, the calculations are as follows:

(1) Since NO is perpendicular to LM, so ∠LON and ∠MON measure 90 degrees.

(2) LO = OM = 2 units.

(3) ΔLON and ΔMON share side ON.

(4) Triangles LON and MON are congruent by the side-angle-side postulate.

(5) The pair of rigid motions that shows that ΔABC and ΔA'B'C' are congruent to each other is

(A) Reflection across the X-axis followed by a translation of 3 units up.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
