Ow... this geometry is sure hard!!
.
Wait a second. Nope.
.
TWO SIDES!!
.
ITT!!
.
CONVERSE ITT!!
.
Converse Isosceles Triangle Theorem!
.
Look at the picture I attached.
.
Two angles equal... THE SIDES ADJACENT TO IT EQUAL!!
.
PERFECTO!!
.
Hope I helped!!

Answer:

The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides

She wrote 5/4+3/4 instead of 5/4-3/4

Step-by-step explanation:

Correct solution:

$\frac{3}{4} + m = \frac{5}{4}$

Subtract-3/4 from both sides

$\frac{3}{4} - \frac{3}{4} + m = \frac{5}{4} - \frac{3}{4}$

Simplify

$m = \frac{5}{4} - \frac{3}{4} \\ m = \frac{1}{2}$

Step-by-step explanation:

x° + 61°+ 68° + 104° = 180°

x° + 129°+104°=180°

x°+133°=180°

x°=180°-133°

x=47°

Answer the following True or False:

Ilia_Sergeevich [38]

False; consider as a counterexample the function f : ℝ→ℝ defined by

$f(x)=\begin{cases}-3&\text{for }x\neq2\\0&\text{for }x=2\end{cases}$

Clearly f approaches -3 as x gets closer to -2, but neither limit from either side is equal to the function's value at x = 2 (that is, -3 ≠ 0), so f is not continuous.

Answer:

Acute Angled Triangle.

Right-Angled Triangle.

Obtuse Angled Triangle

Step-by-step explanation:

a right angle would be 90° angle

obtuse would be over 90°

acute would be smaller than 90°

hope this helps!
