Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are scalene, right angled, isosceles, equilateral.
A right angled triangle is a triangle with one angle equals to 90°.
Statement Reason
∠PQR = ∠RST Given. ∠PQR = ∠RST = 90° (definition for right
angle triangle.
PQ = ST Given
PR ≅ RT Since R is the midpoint of PT, hence PR = RT
ΔPQR ≅ ΔTSR Side-angle-side triangle congruence theorem.
the Side-angle-side triangle congruence theorem
states that if two sides and an included angle of
one triangle is equal to two sides and an included
angle of another triangle, then the two triangles
are congruent. PQ=ST, PR = RT and ∠PQR = ∠TSR
To evaluate the expression given above, we just have to substitute the values assigned to each variable in the expression. The expression would be:
<span>6j23kl−3
We evaluate as follows:
</span><span>6j 23 kl−3
6(3)(23)(7)(33) - 3
95631
Hope this answers the question. Have a nice day.

Answer:11+8t
Step-by-step explanation:
the first two numbers don't have variables but the second two numbers have so basically you just have to do what the sing tells you to do 'subtract' and keep you variable 't' and of course add 3 and 8
Answer:
b=4
Step-by-step explanation:
3(b + 2) - 3= 15
3b + 6 - 3 = 15
3b + 3 = 15
3b = 12
b = 4
Set up the equation 3x+1= 4x-7 and you’ll get your answer
