Answer:

According to the given question if one of the angle of the triangle is 75 degree and the other two sides are of length 2 and 3 units respectively then option C is correct. Only One triangle can be formed where Angle B will be 40 degree. You can figure it out from the steps mentioned below first of all draw an Arc with the length either 3cm or 2 cm that will be the base of a triangle and then from the ending point again cut an arc then after from the starting point that is the point draw  an angle of 75 degree with the help of protactor and extend it to meet the Arc finally you can get the 40 degree.

Hope this helps. Name me brainliest please

Find the length of WR<br><br>If M &lt;WCR = 49 and CR = 7. What is WR
UkoKoshka [18]
We know that
if ∠WCR=49°
then 
measure arc WR=49°-------> by central angle

circumference C=2*pi*r
for r=7 in
C=2*pi*7-----> 43.96 in

if 360°(full circle) has a length of----------> 43.96 in
 49°---------------> x
x=49*43.96/360-----> x=5.98 in

alternative method 
applying the formula
L=(∅/360°)*2*pi*r
where
∅ is the angle in degrees
r is the radius
L=(49°/360°)*2*pi*7------> L=5.98 in

the answer is
5.98 in

The area of triangle PQR is 273 cm. Given that PQ = 12.8cm and PQR = 107°, find QR.​
storchak [24]

\text{Area of triangle} = \dfrac 12 \times PQ \times QR \times  \sin \angle PQR \\\\\\\implies  273= \dfrac 12 \times 12.8 \times QR \times \sin 107^{\circ}\\\\\implies 273 = 6.4 \sin 107^{\circ}  \times QR\\\\\\\implies QR = \dfrac{273}{6.4 \sin 107^{\circ}} = 44. 606~~ \text{cm}

X^2-x-42=<br><br><br><br> factor as the product of two binomials
azamat
I’m pretty sure it’s (x-7)(x+6)

to factor you need it to multiply to -42 and add to -1 which gives you -7 and 6
