Answer:
6. A
Step-by-step explanation:
Qr=1/2 mn = ms
mn=2 ms=12
ln^2=lm^2+mn^2 using phythagoras rule
ln^2=400
ln=20
If you look at the question closely its just asking for the sides added the answer is B 30 + 15 =45 30+18=48
Answer:
27
Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27
9x=27
To find m<3, we can use the angle sum of triangles, in which the addition all angles in a triangle must be equal to 180°.
In this case:
m<3 +52°+29° = 180°
m<3 + 81° = 180°
m<3 = 180°-81°
m<3 = 99°
To find m<4, we can use adjacent angles on a straight line, where the addition of angles on a straight line must be 180°.
In this case:
m<4 + 99° = 180°
m<4 = 180°-99°
m<4 = 81°
Therefore m<3 is 99° while m<4 is 81°.
Hope it helps!
