Answer:
definition of midpoint
Reflexive property of congruence
SSS congruence postulate
CPCTC theorem
Step-by-step explanation:
Step 1: Since, M is the midpoint of the line segment QR.
definition of midpoint
Step 2: The reflexive property of congruence states that a line segment or an angle or a shape is always equal to itself.
Reflexive property of congruence.
Step 3: The SSS congruence postulate states that if three sides of a triangle are equal to three sides of another triangle, then the two triangles are congruent.
SSS congruence postulate
Step 4: CPCTC theorem states if two triangles are congruent then the sides and angles are also congruent.
CPCTC theorem.
<span> ϕ = (1+√5)/2 ≈ 1.618
10.4 * ϕ ≈ 16.8
10.4 / ϕ ≈ 6.4
Answer: b </span>
A ruler to measure the length of an object.
Following the principle of supplements angles, the angle next to the 101 is 79°. 79+38+c(call the third angle c) = 180
c = 180-117 =63° x is supplemental to c so 180 = x +c
180=x + 63
x =117
Given inequality
=> −2(x+1)≥3x+8
=>
now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2
HOPE IT HELPED YOU.
