Answer:

Step-by-step explanation:

The base angles of an isosceles triangle are congruent

The sum of the 3 angles in a triangle = 180°, hence

180° - 112° = 68°

base angle = $\frac{68}{2}$ = 34°

Thus each base angle equals 34° → A

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

triangles
equation
PEMDAS

<h3>given:</h3>

$M\angle T=2x+2$
$M\angle R=3x+1$

<h3>tips and formulas:</h3>

this is an isosceles triangle since two sides are equal therefore $\angle T=\angle S$
a triangle contains 180°

<h3>let's solve:</h3>

according to the question

2x+2+2x+2+3x+1=180

solve:

collect like terms:7x+5=180
substract 5 from both sides:=>7x+5-5=180-5=>7x=175
divide both sides by 7: =>7x/7=175/7

x=25

given:

M∠R=3x+1

substitute the value of x

3×25+1

75+1

noname [10]

Answer:

04 is ten times as great as which decimal. 0.04 = 10 times decimal number . 0.04 = 10 * x. On dividing both sides by 10. x = . x = 0.004. Therefore, Decimal number 0.004
